I got some GT-5000 grip tape about a month ago to use on a few mice that don't have a rubber grip on the side. I tested it on the SteelSeries Sensei RAW, Logitech G303, and Roccat Kone Pure Military.
Here are some pics of the mice with the grip tape:



The GT-5000 grip tape off amazon comes with a couple 2" x 8" strips that can be used on at least a few mice. Pieces can be cut pretty easily to fit perfectly on the sides of a mouse and stick well over curved surfaces, which I cleaned with rubbing alcohol before applying. The RKP was the first mouse I tried it on, and I could do a better job with that mouse, but I don't use it that much. I've been using my Sensei RAW with the grip tape for a few weeks without any issues like edges peeling. I'm not sure how it will hold up over months, but it's meant to be used on stuff like firearms so I think it will be fine. The grip tape should work on smooth surfaces that are plastic, metallic, or rubber coated surfaces like with the Sensei RAW.
The grippyness of the surface is really good, a mixture of coarse and rubbery. When my hand gets sweaty, it still works well, unlike the rubber side grip of my Mionix Castor. I prefer using my Sensei RAW with the grip tape mod to my Mionix Castor now. It also makes the G303 significantly more usable for me (precision gripping and long term comfort with grip tape applied to both sides). I'm fairly impressed with this grip tape and would prefer using it to a built-in rubber side grip.
