oh hey guys uh just casually gaming
with the purchase of a qualifying Intel processor SSD or knuck you could
instantly win an Intel gaming jersey and be entered in the draw for the ultimate
system click now to learn more the first and most important thing about this
mouse is the optical sensor featuring logitech's delta zero and fusion engine
i'll get into exactly what the fusion engine does in a moment but first i want
to test their delta zero feature which basically means no cursor acceleration
as i have some pretty seriously deeply rooted trust issues when it comes to
most manufacturers and their claims about acceleration a quick and dirty
explanation of mouse acceleration is this if you disable it moving your mouse
from point a to b along a surface without acceleration should result in
the cursor on your screen moving exactly relative to the movement of your mouse
independent of the speed of which the mouse is moving
if you were to start at a move halfway to b extremely quickly shake the mouse
around for a little while and then go extremely slowly to b it would still
land on b if you enable acceleration moving extremely quickly the same
distance on the mouse pad will cause your cursor to overshoot b's position on
the screen and then repeating the same movement but very slowly will cause the
cursor to fall short of b's position this is fine for average users who want
to move their mouse very slowly when trying to click on something more precisely but it's not desirable for
gamers who want precision of their muscle movements to translate directly
to the screen without any janky randomness it seems like this is a
non-issue since aside from gaming mouse drivers Windows allows pointer
acceleration to be disabled except that many modern gaming mouse sensors have
inherent acceleration that cannot be turned off so to calm anxiety we tested
g402 sensors by grabbing our camera slider and just doing a few
modifications i replaced the traditional soft stopper method with dual heavy duty
clamps to reduce travel when the slider bumped into them
i then put the slider on the table and lowered it pretty much as far as it could go using a velcro strip to secure
the mouse to the bottom of the slider then for measurement i put a grid
overlay on my monitor after all this setup i tested it with a
variety of movements and i'm happy to say that as far as i can tell the g402
features what is known as a perfect sensor with no inherent acceleration
kudos logitech next up is the fusion engine i was
talking about earlier logitech is using a gyro and an accelerometer to augment
their already awesome optical sensor if you're running at a low dpi setting and
need to whip your mouse insanely fast in order to pull that super sick 360 no
scope at the end of your mega dope montage video it is technically possible
for you to outpace an optical sensor if you do manage to outpace the optical
sensor it can potentially cause the cursor to jutter or even drastically
jump around which is bad with the fusion
engine and the gyrometer and accelerometer we'll try to fill the
holes in the data stream to avoid this to test this out Linus and i had a
contest of sorts where we battled to see who could whip the mouse the fastest in
terms of ips or inches per second minus one to his extensive master badminton
skills which he has honed over many years of extremely vigorous training so
it works as advertised kudos again but even though it worked i left logitech's
sensor monitoring tool on for a night of gaming and just tried to ignore it and
play normally to see what would happen it seems that i never actually exceeded
84 ips which means this feature is unlikely to ever actually kick in for me
but i'm not a professional gamer if you're a low sensitivity gamer and you
do end up purchasing the g402 and you find that you get into the speeds where
the fusion engine really benefits you please message me on twitter or some
other medium as i'd love to hear more about your experience which brings us to
the software setting the 240 to 4000 dpi
sensors multiple sensitivity levels was easy enough and it allowed for fairly
specific setting as it was able to increase in increments of 80. you can
also set your polling rate to 125 250 500 or even 1 000 reports per second
after getting all that technical stuff out of the way you can have fun with the right side of your brain by playing with
the customizable lighting you're able to set brightness level change the speed or
disable breathing mode entirely and change the deep if dpi lighting is
always on or just illuminated when you are changing things and last but not
least is turning off the lighting effects when you haven't used your mouse for a specific amount of time handy for
those of us who have our computers in our rooms so that was fun but now it's
time for real world use of impressions in terms of shape feel and ergonomics of
the unit when compared to the g502's futuristic alien looking aesthetic the
g402 is definitely more conservative but still does have some flair it's rocking
eight buttons including forward back dpi up dpi down dpi shift left click right
click and middle click and they can be programmed to execute various functions
keystrokes or even multi-key macros using logitech software so basically
even if you're one of those guys who is religiously against dpi shift buttons
you can set that button to anything from play next song functionality to spamming
kabba kappa kappa or razer dongerz in chat unfortunately though scroll up and
scroll down were not included in the key binding options after all that we're
left with a few takeaways when compared to the g502 the g402 is definitely a bit
more conservative it's down to eight buttons from 11 it
doesn't have a free spinning or tilting scroll wheel it doesn't have a
customizable weighting system it lacks some of the nicely textured soft touch
rubber gripping the light isn't quite as bright
it doesn't have a braided cable the swooped out part for your thumb isn't
nearly as accommodating and the left and right click don't feel quite as sharp
and responsive as the g502 but they still have a 20 million click rating
which is nice but hold on now that's actually not that bad on one hand you
have the g502 with its beautiful sensor and laundry list of features on the
other hand you have the g402 with a different but still beautiful sensor
which is ARM in ARM with a powerful but possibly not needed for everyone at
least fusion engine while the g402's laundry list of features is considerably
shorter than the g502 it still feels great in hand i mean you still have the
fundamental ergonomic quality of a logitech mouse which too many people
myself included feels great in your hand
and you've got one other thing in your hand that feels great too
20 bucks the g402 is 60 compared to the g502's 80 price tag so that's a lot of
most for your money and the review is pretty much over but i have one more
closing thought thank you logitech for working on meaningful performance
metrics instead of just focusing on dpi
which many people are just going to lower anyways they don't even have their
dpi blasted on the front of the box and it's clear they're more focused on
things like their delta zero and fusion engine technologies i'm tired of seeing
companies dump high-end flawed mice
year after year and it's nice to see a shift in focus speaking of a shift in
focus today's video is sponsored by Gigabyte auras x7 v2 gaming notebook
this is the thin and light sli gaming notebook that we compared against a not
so thin and light notebook in the video in the annotation here
with two GeForce 860ms in sli an Intel i7 4860hq processor a 17.3 inch 1080p
display a one terabyte hard drive and a few different options for SSD and RAM
capacities all packed in a chassis that's less than 0.8 inches tall this is
an absolute beast that you can pack in your backpack without breaking your back
as a surprisingly good keyboard solid heat dissipation from its rear exhaust
setup and more than acceptable noise levels for a thin notebook all which
make the Gigabyte auris x7 v2 an ideal product for someone looking for a
notebook that's suitable for everyday use as well as gaming so if you're in
the market for a gaming notebook be sure to check out pricing and availability
for the x7 v2 using the link in the video description let me know what you
guys think about their delta zero and fusion core technologies as long as what
do you guys think about our testing methodologies for stuff like acceleration also if you would like to
save money getting the 402 or if you're more kind of into the baller style
status of the g502 let me know all that kind of stuff in the comments down below
where you should also be liking disliking subscribing sharing and
otherwise distributing this video and if you want to post somewhere else because
you're kind of not into youtube jump over to the forum post there and let me
know what you think there if you don't like the ads on the forum become a contributor and as always thank you guys
for watching i'll see you next time
