00:00:00,000 --> 00:00:06,200
I might have been wrong about Razer's gaming mice, and I'm really excited to find out just how wrong I was

2
00:00:06,200 --> 00:00:10,160
because today we're unboxing the Razer Viper V4 Pro,

3
00:00:10,160 --> 00:00:13,480
the latest in high-end competition from Razer

4
00:00:13,480 --> 00:00:19,480
for the G Pro X Superlight. It is an ambidextrous mouse in the light category

5
00:00:19,480 --> 00:00:24,560
with all of the bells and whistles you could ever want from a mouse and maybe some more,

6
00:00:24,560 --> 00:00:27,800
as well as some major changes from Razer

7
00:00:27,880 --> 00:00:32,280
that make me actually want to consider their products for the first time in a long time.

8
00:00:32,280 --> 00:00:38,640
In the box, we have our mouse, we have our dongle that looks more like a chocolate

9
00:00:38,640 --> 00:00:43,360
than a technological device. I don't often get the urge to like lick things,

10
00:00:43,360 --> 00:00:47,320
but I really want to lick this. Luckily, what I can't explain is that it is good

11
00:00:47,320 --> 00:00:51,760
for 8,000 Hertz polling rate. It has LED indicators for a multiple of purposes,

12
00:00:51,760 --> 00:00:54,800
which we'll get into, and it's powered via USB-C,

13
00:00:54,840 --> 00:00:59,840
although this could be the most recessed Type-C port ever made.

14
00:01:01,160 --> 00:01:05,280
Like you, on the camera, you can't even see the frickin' USB in there.

15
00:01:05,280 --> 00:01:09,080
You just see a hole and then like a little whisper of metal reflection.

16
00:01:09,080 --> 00:01:14,480
They really don't want you to use a non-Razer cable. Thankfully, it comes with one,

17
00:01:14,480 --> 00:01:21,580
and these Razer cables are generally really high quality. This is another braided cable, just over six feet.

18
00:01:21,580 --> 00:01:26,680
Lastly, we have our instructions. Great, this is actually useful, not this.

19
00:01:26,680 --> 00:01:30,720
We got grip tape, if you're so inclined.

20
00:01:30,720 --> 00:01:35,800
I think that Razer has greatly improved the feel of their plastic on their high-end mice

21
00:01:35,800 --> 00:01:39,800
over the last five years, so I would probably prefer not to use a grip tape,

22
00:01:39,800 --> 00:01:43,360
but that's an actual value add, which you might enjoy.

23
00:01:43,360 --> 00:01:46,840
Getting to the mouse itself, like all good gaming mice,

24
00:01:46,840 --> 00:01:51,720
it's a pretty no-frills affair. We got our six total buttons,

25
00:01:51,720 --> 00:01:58,240
including the main two top ones, with Razer's new switches that are rated for a million clicks.

26
00:01:58,240 --> 00:02:01,560
They're supposed to be 12% more responsive.

27
00:02:01,560 --> 00:02:05,760
They are loud. These are loud clicks. This is not an office mouse,

28
00:02:05,760 --> 00:02:09,520
and if you share an office with me and use this mouse, we will not be friends.

29
00:02:09,520 --> 00:02:13,840
However, I would like to feel your mouse, because these are nice clicks all the way up,

30
00:02:13,840 --> 00:02:18,680
all the way down, very consistent, very satisfying tactility.

31
00:02:18,680 --> 00:02:25,040
That's a good start. How's the scroll wheel? It's an optical scroll wheel, and it feels quite solid.

32
00:02:25,040 --> 00:02:29,040
It's a wide-shape, good rubbery feel, good tactility,

33
00:02:29,040 --> 00:02:33,200
and the click feels pretty much just right.

34
00:02:33,200 --> 00:02:37,000
I feel like the wheel wants to go a little too easy,

35
00:02:37,000 --> 00:02:40,800
where when I click, it almost wants to rotate every time.

36
00:02:40,800 --> 00:02:44,160
Not a huge deal. I generally don't use middle mouse click.

37
00:02:44,160 --> 00:02:50,200
I usually assign that to something else, including the side buttons, like this front and back button.

38
00:02:50,200 --> 00:02:53,760
They're quite small, however, it's proportioned to this mouse.

39
00:02:53,760 --> 00:02:56,800
I don't hate the way they feel. The click is quite good, good tactility

40
00:02:56,800 --> 00:03:00,080
all across of the button, but there's something about this plastic

41
00:03:00,080 --> 00:03:04,160
that feels different or cheaper, or maybe it's just the way that it's raised,

42
00:03:04,160 --> 00:03:08,060
and it's kind of straight edges. It doesn't feel as premium as the rest of the mouse.

43
00:03:08,060 --> 00:03:11,200
It's a little sharp on a comfortably rounded mouse.

44
00:03:11,200 --> 00:03:16,600
We also have our power and DPI button, which is underneath, which is a less useful spot

45
00:03:16,600 --> 00:03:20,560
than on top. It also allows the top to be nicer looking.

46
00:03:20,560 --> 00:03:23,720
We have our Type-C port, and we have our LED indicator on the front.

47
00:03:23,720 --> 00:03:29,000
Right now it's looking for a pairing, so it's gonna keep flashing until I give it its daddy.

48
00:03:29,000 --> 00:03:33,960
On the bottom, we have our quite large glide skates. These are 100% PTFE,

49
00:03:33,960 --> 00:03:39,080
which is the silver standard of glide skates. Glass would be nice, but it's fine.

50
00:03:39,080 --> 00:03:44,280
What is kind of gold standard right now is some new sensor technology.

51
00:03:44,280 --> 00:03:48,760
Razer has the Focus Pro 50K optical sensor Gen 3.

52
00:03:48,760 --> 00:03:55,080
Rolls off the tongue. It's good for 50,000 DPI, 930 IPS, and 90 Gs,

53
00:03:55,140 --> 00:03:59,020
which is way more than you're ever gonna need. But when you're pairing with 8,000 Hertz,

54
00:03:59,020 --> 00:04:04,140
as well as some in-class leading latency, every little bit can help and it all adds up.

55
00:04:04,140 --> 00:04:10,120
And when you're buying, you know, your Ferrari, you don't want Lincoln specs, you want speed.

56
00:04:10,120 --> 00:04:14,560
Anyone else is really important? Let's see what we're working with, baby.

57
00:04:14,560 --> 00:04:18,160
50 grams! That is not the lightest mouse in the whole world,

58
00:04:18,160 --> 00:04:23,080
but it is so far beyond the point of diminishing returns. 50 grams, plenty light.

59
00:04:23,080 --> 00:04:28,080
And that's pretty good considering that Razer claims that this is good for up to 180 hours of battery life

60
00:04:28,080 --> 00:04:32,280
at 1,000 Hertz or 45 at 8,000 Hertz.

61
00:04:32,280 --> 00:04:35,640
So if you want extra battery life, you know, you can sacrifice a little performance,

62
00:04:35,640 --> 00:04:41,160
or you know, you want Ferrari, you go speed. You want segways, you go now.

63
00:04:41,160 --> 00:04:46,720
We're back, and I'm so excited to show you the greatest upgrade that has ever happened to Razer products.

64
00:04:46,720 --> 00:04:49,240
No longer do you need to download Razer Synapse.

65
00:04:50,280 --> 00:04:54,180
Freaking web app! Oh yeah, come on, it's just in beta right now,

66
00:04:54,180 --> 00:04:57,360
but even beta is gonna be better than whatever the f*** we were doing before.

67
00:04:57,360 --> 00:05:00,800
Let's see if it works. Advice, Viper Vifro.

68
00:05:00,800 --> 00:05:04,360
Oh, thank you so much, Razer. This is the way forward.

69
00:05:04,360 --> 00:05:08,520
Web apps, don't make me download freaking garbage, bloatware, spyware crap.

70
00:05:08,520 --> 00:05:13,160
This is the future! First things first, we can change all the button assignments

71
00:05:13,160 --> 00:05:16,360
other than the left click, which can be problematic.

72
00:05:16,360 --> 00:05:19,740
We can use HyperShift so that we can basically assign an alternate key.

73
00:05:19,740 --> 00:05:24,180
We got our indicator LED options. One is, the first one is gonna show us

74
00:05:24,180 --> 00:05:27,520
our connection quality, then our battery level, then our polling rate.

75
00:05:27,520 --> 00:05:32,340
You can turn them off, which is nice. But I actually think that having the polling rate

76
00:05:32,340 --> 00:05:36,340
is a pretty nice one. Otherwise, you can have your DPI stage on this.

77
00:05:36,340 --> 00:05:41,420
That makes a lot more sense than having it on the mouse because this actually I could have

78
00:05:42,320 --> 00:05:45,880
within eye shot of my monitor so I can look at the dongle and see.

79
00:05:45,880 --> 00:05:49,960
I actually think that's a smart upgrade instead of adding more weight to your mouse.

80
00:05:49,960 --> 00:05:54,920
Put it on the dongle. Next, we can change our DPI settings. We can separate the X and Y axis.

81
00:05:54,920 --> 00:05:58,660
We can enable up to five different settings

82
00:05:58,660 --> 00:06:02,360
and move them around. I know that I just want 800. So I'm gonna disable everything

83
00:06:02,360 --> 00:06:06,420
except that it looks like you have to have two on,

84
00:06:06,420 --> 00:06:11,480
which is interesting. I would like that to be a thing that mice manufacturers don't force me to do

85
00:06:11,480 --> 00:06:14,680
is have two profiles. I know exactly what I want

86
00:06:14,680 --> 00:06:17,920
and I don't need my button to accidentally switch it partway through.

87
00:06:17,920 --> 00:06:21,480
That being said, I would know because my frigging light on my dongle

88
00:06:21,480 --> 00:06:25,200
would tell me I have the wrong settings. Next, we have our power settings.

89
00:06:25,200 --> 00:06:28,680
So we can turn up the speed at which it goes to sleep

90
00:06:28,680 --> 00:06:31,680
or low power mode. I don't ever want you to go to sleep.

91
00:06:31,680 --> 00:06:36,520
And then we can calibrate. We can enable asymmetric cutoff, which will divorce our lift off distance

92
00:06:36,520 --> 00:06:41,520
and our landing distance. We want it as low as possible unless we have weird tracking issues.

93
00:06:41,520 --> 00:06:46,400
Then we have our advanced, which enables us to have a dynamic sensitivity,

94
00:06:46,400 --> 00:06:49,440
which definitely could be your thing.

95
00:06:49,440 --> 00:06:53,620
The other thing that I like that I've seen more and more is actually a rotation setting.

96
00:06:53,620 --> 00:06:57,160
So depending on which angle you have your mouse,

97
00:06:57,160 --> 00:07:02,920
it makes adjustments based on that. I think I usually keep it around like the seven,

98
00:07:02,920 --> 00:07:06,720
that's a bit more, like let's say call it nine. Nine degrees.

99
00:07:06,720 --> 00:07:10,040
So now the software knows that I'm holding it at an angle

100
00:07:10,040 --> 00:07:13,680
and is making some kind of adjustments for that.

101
00:07:13,680 --> 00:07:17,320
So that's pretty cool. Again, something you're gonna want to get used to

102
00:07:17,320 --> 00:07:20,600
not just switch over and forget that you did.

103
00:07:20,600 --> 00:07:25,680
Let's game. First impressions. This feels like a very, very good mouse.

104
00:07:25,680 --> 00:07:30,080
Makes sense. Our Labs testing show that this is about as good as it gets

105
00:07:30,080 --> 00:07:36,000
just above 0.6 milliseconds, both over wired and dongle at 8,000 Hertz.

106
00:07:36,000 --> 00:07:39,600
That's pretty fantastic. And what we found out recently in our video

107
00:07:39,600 --> 00:07:45,200
where we tested if input latency matters is that every millisecond of input latency

108
00:07:45,200 --> 00:07:48,560
does friggin' matter. Go watch that video if you haven't watched it.

109
00:07:48,560 --> 00:07:52,080
It's hard to comment too much on top end gaming mice because they're all pretty darn good,

110
00:07:52,080 --> 00:07:55,680
but like this I feel so connected

111
00:07:55,680 --> 00:07:59,760
to what's happening on screen. Kind of more impressed than I thought it would be

112
00:07:59,760 --> 00:08:03,640
about a razor product. What I will say is it feels like the balance of the mouse

113
00:08:03,640 --> 00:08:07,960
is a little further forward than I'd expect. Like the back feels very, very light.

114
00:08:07,960 --> 00:08:13,120
Not necessarily a bad thing, just something to note. We also tested the sensor accuracy.

115
00:08:13,120 --> 00:08:18,040
And while it's not the best that we've tested, it's totally within the realm of pretty good.

116
00:08:18,040 --> 00:08:21,120
And you would get used to it pretty darn quick.

117
00:08:21,120 --> 00:08:24,640
I'd say overall, razors on a pretty good trajectory.

118
00:08:24,640 --> 00:08:28,680
It sounds like they're listening to their users. They're making a pretty solid product.

119
00:08:28,680 --> 00:08:32,120
And it seems like on paper at least it should be more reliable than some of the products

120
00:08:32,120 --> 00:08:36,040
I've tested in the past. You're gonna be paying for all this performance.

121
00:08:36,040 --> 00:08:40,880
It's $160, not the most expensive gaming mouse there is,

122
00:08:40,880 --> 00:08:44,960
but it's above what I usually consider to be necessary

123
00:08:44,960 --> 00:08:51,160
for pretty top end performance. However, that's not mind blowing or collector price

124
00:08:51,160 --> 00:08:54,400
like we've seen in other razor products. And it's a very good package.

125
00:08:54,400 --> 00:08:58,240
So let us know in the comments. Would you consider a razor product?

126
00:08:58,360 --> 00:09:02,000
Are you like me that you're like absolutely not for quite a long time?

127
00:09:02,000 --> 00:09:06,400
And let us know. If you wanna watch more ShortCircuit videos, you can check out the time we unboxed the Keychron M5.

128
00:09:06,400 --> 00:09:10,600
It's a vertical mouse, but those innards are inside of all of the Keychron M series

129
00:09:10,600 --> 00:09:15,560
lineup and those are really good value. And if you want a little more education on input latency,

130
00:09:15,560 --> 00:09:18,600
you should check out that LTT that we produced a few months ago.

131
00:09:18,600 --> 00:09:22,520
It's got some pretty cool people in it. Like baby no money. Yeah, he's a gamer.
