The Level 10 M mouse from Tt eSPORTS shows a lot of promise but ultimately fails to deliver on a number of aspects. First and foremost, the comfort-enhancing features work, but the added bulk means that the gains are questionable at best. During our testing, the fatigue associated with use was higher than that of more conventional mice like the Zowie AM or Mionix NAOS 5000. This mouse is made for MMORPG and RTS games, but its comfort in such scenarios is far from optimal.
Button placement and shell design only make this mouse interesting to a very limited number of people looking for a very heavy mouse with very high sensitivity. The sensor performs quite well if you look past the drift issue. The buttons used are of a very high standard, but the mouse is, unfortunately, not that great as a whole.
The adjustment system definitely works, and you do feel the changes when you manipulate the two screws. The implementation compromises the rigidity of the palm plate assembly, since the forward hinge cannot be locked into position. This leads to a somewhat shaky palm plate that can be pretty annoying during gaming sessions. It does depend on your type of grip, but it is nearly impossible to eliminate completely. The build quality on some of the parts does not look very high-end. Take, for instance, the aluminum base plate: it is crudely made.

If it had been 65 g lighter, had side plates with better contours, and better placed buttons, it could have easily bested the CM Storm Sentinel Advance II in every way. As it is right now, the Level 10 M just seems overpriced despite the many novel features it has over the, in comparison, fairly standardized CM Storm Sentinel Advance II.
