Compared to the ZOWIE FK1
The ZOWIE fk2 is basicly just a smaller version of the FK1.
Compared to the ZOWIE FK
Nothing besides the new sensor and a new lense to achieve the low lift off distance. These small but important changes would be enough to justify switching to the new fk1 or fk2 though if you need a better performing sensor and lense.
Compared to the ZOWIE AM
The design is still ambidextrious, it still have the same sensor but it feels like a completely different mouse because of the change to a more | | shape than the / \ used in the ZOWIE AM. Other changes are a better scrollwheel with and a sensor that works much better with ZOWIEs custom lense, which I will get into later. Other than that the there's a new coating and yellow theme instead of the red one used in the ZOWIE AM. So to sum it up the features are:
• Ambidextrous mouse developed for claw grip usage
• Two thumb buttons on both sides to comfortably serve left- and right-handed users
• Plug and Play (no drivers needed)
• Easy to switch between left- and right-hand functionality
• 400 / 800 / 1600 / 3200 DPI adjustment
• Adjustable USB report rate 125 / 500 / 1000 Hz
• Perfect lift-off distance = 1.5 ~ 1.8mm
• Operating system: Win2000/XP/VISTA/7/8; Mac OS X v10.2 after
The sensor might have been the biggest drawback of the ZOWIE FK and ZOWIE AM, despite actually being a very good sensor. But the lense seemed to hold it back in terms of perfect control speed and even with the stock lense, the avago 3090 was never perfect because of the high lift off distance. The avago 3310 is a different story though, with both a VERY high perfect control speed and in the ZOWIE FK2 and FK1 a very low lift off distance too. The sensor behaves pretty much perfect in terms of control, speed, lift off distance and won't hold anyone back from performing their best. Also the sensor now does 400/800/1600/3200 which should be enough for anyone and are much better options imo than the unusual dpi options the AM/FK have. Most pro gamers I've seen usually use around 800dpi and 1150dpi that the AM/FK have is simply too fast.
Below are my results for perfect control speed using enotus mouse test. I have only done the tests using 1000hz since I think there's no reason to use a lower rate. I can post more results though if requested.
I tested the mouse for prediction and jitter also and the results are below. There's no jitter or prediction, and there was no tracking bugs either as with the ZOWIE AM/FK have on some light colored surfaces.
This is ofcourse going to be very subjective but I will try my best to be as objective as possible.
I have compared it to 4 other ambidextrous mice that I have tried
Very comfortable mouse. Very short and fits both hands. If you have small hands then this can definately be used all day without any discomfort. The weight is about the same as the g100s so it's very easy to move around.
Great ambidextrious shape that will fit both hands.Its small and definately not made for larger hands or palmgrip. Using it for a whole day gives some discomfort in the thenar region of the hand and will getting the "gamer mark". The weight is around 70g and that combined with the sensor makes me miss some shots sometimes
Steelseries sensei raw
Again a great ambidextrious shape that works well for all types of grips depending on the size of your hand. In my hands it's a bit on the larger size and feels a bit too wide. The weight is around 90g and it feels very balanced.
Very similar to the steelseries sensei and feels much much different than the ZOWIE AM. The shape is very easy to hold and will work perfectly with all grip styles, although you won't be able to palm it if you have large hands. It feels more \/ shaped which imo gives a much much better grip than the ZOWIE AM which have a more /\ style shape. Coming from a steelseries sensei raw or ZOWIE AM you will quickly notice that it's not so tall though and it feels much smaller than the sensei raw, so it might take a couple of days to get used to the lower height and overall feel. The side buttons are positioned in a much better place than both the sensei and the ZOWIE AM though and I haven't clicked them by mistake yet or having trouble finding them while gaming.
Overall the ZOWIE FK2 definately have the most comfortable shape of them all if you have a small or medium sized hand. If you have large hands the sensei raw is probally more comfortable.
ZOWIE is using their own switches in all their mice and depending on various things like placement of the switches they can be very hard to press.
They are harder to press than most gaming mice, but they give a GREAT feedback in terms of feel and sound. Also they have a very short travel and shorter than all mice with omron switches(except the ninox velocity/aurora) so despite the higher pressure required, it's easy to double click
The ZOWIE FK buttons feels easier to activate than both the ZOWIE AM and the ZOWIE Mico and about the same as the ZOWIE EC's. While it's still a bit harder to press than the average gaming mouse that I have tried, it's still comfortable to use all day.
From my findings highest to lowest amount of pressure required to activate the buttons:
Mionix naos 8200
Razer deathadder 2013
cm storm spawn
The scrollwheel definately feels better than the scrollwheels in the older ZOWIE models but it takes just a little longer than normal to scroll through a document.
Like all other ZOWIE mice the ZOWIE FK2 doesn't come with any software. This is both a good thing and a bad thing,
The good thing is that you avoid having to rely on a software that might crash or drain your memory.
The bad thing is that you have to use a third party software or rely on ingame control settings if you want to assign the buttons to other things than the default. But pretty much all new games allow you to assign mousebuttons to a command so this shouldn't be an issue.
Luckily you can change everything else without using the software, from the dpi, to the polling rate and even which side buttons are active.
This part has always been difficult to write about in my reviews since mostly I have only used the mice I review for a week or so. So this time I gave myself a much longer period to test it out
ZOWIE is still using the same cord which in my opinion is the best cord out there.It is neither too thin or too thick and it is very flexible so you can feel the mouse moving in the direction YOU want.
The mousefeet are big and glides well and the mouse comes with an extra set of mousefeet so you won't need buy new for a very long while.
Like the first ZOWIE FK, The coating is one of the biggest changes from the ZOWIE AM and it feels super smooth and easy to grip. Having used the mouse for more than a month I can tell that it's more resistant to sweat than the usual rubber coating used normally in gaming mice. Another great thing is that it's easier to clean.
Putting everything in to account the ZOWIE FK2 overall is probably my favourite mouse that I have ever tried and it's hard to find any flaws with it. In terms of shape, weight and build quality it is pretty much perfect for anyone using clawgrip or fingertip. Sensor performance it's greatly improved since the ZOWIE FK and should be more than enough for anyone. The switches feel good but can't can get a bit tiring in moba and strategy games because of the higher amount required to activate, so If I had to change anything it would be to make them a bit easier to press.
So to sum it up
+Very good perfect control speed
+High performance at all dpi levels
+No tracking bugs
+Very low lift off distance
+Good balanced weight(85g)
