For 4 months now, I've been using and enjoying these Hyperglide mouse skates on my Intellimouse Optical: https://www.amazon.com/gp/product/B00X9FGBI8
Just a few minutes ago, I began trying Hotline Games Mouseskates. Namely, these: https://www.ebay.com/itm/272975857267
(I bought the Competition 0.6mm skates)
While there was really nothing wrong with the Hyperglides, the Hotline Games mouseskates are noticeably better. I started with just 4 to see if 0.6mm was enough. It wasn't, at least not with the Intellimouse Optical. So, I added 4 more for a total thickness of 1.2mm, and now it's just awesome. I had no idea my mouse could feel like this! I'm actually experiencing relief here.
They were also much easier to install. The Hyperglides require you to peel the backing off of each individual skate, and it can be very difficult and as I learned the hard way, it's also possible to peel off the adhesive right with the backing! The Hotline Games are simply stuck to a 3M sheet and the adhesive is somehow permanently applied to the skates. I even had to remove 1 of them from my mouse and reposition it after finishing the installation process, and the adhesive didn't come off the skate! With the Hyperglides, the adhesive peels right off the skates.
The best part? The cost! The Hyperglides were about $15 for 8 skates of 0.8mm each (which are thick enough for this mouse). The Hotline Games pack has 16 skates which, for me, is 2 sets - all for only $7. They also include 4 alcohol wipes and a very nice microfiber cloth with their logo permanently pressed into it. It's classy.
There is 1 negative thing though. For some reason, the skates were oily or greasy or something. As soon as I removed the sheet of skates out of the plastic sleeve/bag thing, I noticed it. So, I simply cleaned them with one of the alcohol wipes!
Anyway, so yeah, seriously: if you are looking for extremely good mouse skates, get these!
Don't even hesitate.
Oh, and don't forget to remove the protective plastic film from each skate!
