Gamesense Meta Review
They're obvioulsy going after the hardcore market. As TPU notes this mouse is an obvious Zowie S2 clone. IMO, this is welcome, because I'd like more competition offering lower prices for well-built mice with simple, proven designs and quality materials/sensors/performance/firmware than the unreliable Chinese junk that populates the budget offerings on the market, currently, or the effete overpriced bullshit like Finalmouse.
The most negative issue suffered by the mouse was the consistent 7.5% positive deviation of the CPI (aka DPI). That's really not an issue if you've read the review because if you're a player who uses an 800 DPI, for example, you can just set it to 745 instead. Meanwhile, it was pretty much perfect everywhere else, and had phenomenally low latency.
Rtings also scored it very positively:

This
mouse is $45 directly from their website, currently ($5 cheaper than the
Amazon price). Obviously Logitech is the market leader, and this price places it head-to-head against the
G403 Hero. Not sure how well it will do, there, but it's nice to see another company throw its hat in the ring alongside the likes of Logitech, Razer, Zowie, Roccat, VAXEE, HyperX, XTRFY, etc.
