THERMALTAKE eSports Black v2
I decided to use this gaming mouse as a result of a couple of years of testing Logitech G600 and Razer DeathAdder ambidextrous gaming mouse.
I was in doubt at the beginning but this TT Thermaltake eSports Black v2 is definitely an all-terrain since I left using my old Logitech M-100 optical mouse.
This one have multi-profile setup, so I can switch between the needed sensitive and precision for illustration to a necessary gaming setup and key-binding.
The pros:
It’s comfortable.
Intuitive software setup
Precision (4 levels to set from 100 to 5700dpi)
Weight (It has 5 little removable 4.5gr weights)
Price
Just one con:
As the most laser gaming mouse, it doesn’t work on classic gel ergonomic mousepads, so you must need to get one neoprene pad or similar.
Update (2020): still 5 years using it and don’t get any issue with this (and almost still don’t need to unbox the other brand-new Black v2 I have in case this one should fail).
