I love this mouse, not having any of the issues noted in this thread. Like the back dragging -- isn't this a question of grip? I'm guessing users who put more weight toward their palms might get this. Because I'm not getting any drag and I use a 5mm mousepad. I don't think the mouse feels cheap at all -- I think the light weight might give that impression to some, because this seems an unusually light mouse. My only complaint is that the clicks are loud. Not unusually so for a gaming mouse; but it's brutal going from a Logitech to this. Side buttons I can't comment on, I don't use those; I've always found that to make a side button as fast as a keystroke or M1 M2, my thumb has to be pretty much right on it, and the non-natural grip hurts my play more than the extra button helps.
I didn't choose this mouse for the sensor, I chose it for the size, shape, weight, price, and **no mesh on the cable.** But I have to say -- using this mouse, my aiming is so much better its crazy. I don't know if its the sensor or the shape/weight, because I'm going from an aggressively ergonomically shaped 150+ gram wireless mouse to this, which is what, 85g? Use a bungee/tether and this Revel is weightless, it's crazy, it's like I'm aiming just using my hand.
Anyway -- I'm hardly Rocket Jump Ninja or anything, my advice on gaming mice shouldn't carry weight at all lol, but man I really like this mouse. And I tried a bunch, pretty much every gaming mouse Amazon carries that's a Prime item. I kept 2, this and the Roccat Kone Pure Military. The Nixeus Revel is now my daily driver and gamer, and KPM I kept because it's $25 and I'll just hold on to it as a backup. I like the KPM too, and I prefer the KPM buttons and coating, but the Revel is much more comfortable. And man what a great price. Only the Camo Charge color KPM beats it imo and that's obviously a steep discount for an unpopular color, the other KPMs cost much more.
Still undecided on the dpi steps. 8 is a lot; but with only one button to change dpi, no software, and 400 dpi increments, you're probably not going to shift back and forth in-game with this mouse anyway.
