Regardless of how you feel about the design of this mouse, its individual adjustment options are a definite high point. Although it doesn't have the Razer Ouroboros’ length adjustment, the Level 10 M can be adjusted 5 mm in height. The top can also be tilted five degrees to either side. This lets the mouse rest more naturally in different hand sizes, and it gives righties and lefties a more customized fit. It’s only too bad that you're stuck with a one-size-fits-all length.
Anyone with large hands or long fingers is bound to have problems manipulating the four-way button that switches between DPI settings without some practice. The other side buttons are better-positioned.
Thermaltake includes a small six-point screwdriver for making adjustments.
Adjusting Thermaltake's Tt eSports Level 10 M takes some force, but the custom settings remain stable over time. They don't wriggle loose or slowly revert to default (Ed.: I can't even say that for my Herman Miller Aeron chair!). The mechanism used is both effective and dependable.
Dangit, which mouse is this? The picture shows too little of it for me to tell!
Hah there may be hope for you yet :)
I ask because I use fingertip grip myself, and I am inclined to think that simply keeping the bulk of your hand off the mouse does a lot to reduce sweating. In fact, the only places that get sweaty are where the fingertips go, just like in the picture of the Level 10 M!
