Amazing build quality, Perfect Shape! Switches eh...

Love almost everything about this mouse. The build quality is top-notch, the shape is G.O.A.T, and weight of 55g feels great, and the sensor is top-tier.

My only issue with the mouse is with its switches. They are optical which is cool as it prevents double-clicks... BUT... they sound kinda "hollow", feel a bit "flat", and are simply not stiff enough. What I mean by "flat" is that the switch's "springiness" is not strong enough for my taste; I wish there was more post-travel velocity. That is, the mechanics of the switch (plunger) feels a bit weak & makes it hard to be consistent when spam-clicking (or butterfly-clicking) and quite easy to accidentally click.

Absolute banger!

IMHO this is the ambi mouse of the year! 4k, 55-gram solid shell, well known S2 inspired shape at a value focused price point. Tracking is superb with this 3395 implementation. Clicks feel snappy and tactile with some of the lowest pre and post travel of any mouse I own. Control software is easy to use. Skates feel premium as do the included grips. This is appreciated as I would usually spend extra on purchasing premium grips and skates from a third-party vendor. My only cons would be the coating feels a little less premium, just like the first gen pulsar X2's but a little more textured. A move to browser-based software would be a step forward as well. A 'quick setup' guide for paring the 4k dongle would be appreciated too, it took a little while to figure that out.
All in all, exceptionally well done!
This became my main as soon as it landed on my desk, replacing mice that cost near 3 times the price.

Good product, but disappointed

I was expecting the exact shape as the Zowie S2, but the hump is much flatter. As a result I'm quite disappointed because the in hand experience is quite different than an S2, but the mouse is still of good quality.

Exceeded expectations

I collect and review mice, currently over 40 plus wireless mice. The outstanding craftsmanship in this mouse genuinely had me giddy once I finally received my copy. The click feeling is the most satisfying of any mouse I have used. I often review mice so I was sure to run my copy through the paces and the integrity is top tier. Since first trying the Aria, I have been keeping an eye on Fantech releases and will continue to do so as they offer S-tier mice at reasonable prices.
