Peace, mercy, and blessings of God be upon you. I used the mouse for two months and three days, then I bought a second mouse. It has esptiger ice v2 skates installed, which are very good and known to be among the best skates. I even bought them for my new mouse. I used the grips that came with the mouse box and threw them away, I didn't like them, but the other items are available. I used the mouse a lot during these two months, I play a lot, but I wipe it with a wet wipe every day, so the mouse is clean, don't worry.
