This was done by Haier's authorised technicians mind you.
The installation was free yes, but I wasn't told it was going to be low quality.
If we employ a private contractor for installation, they void our warranty. If we don't, they do this.
I work building IT. I have replaced one employee's mouse every 2 months since ive started. Employee claims that they do not eat at their desk. It gets so bad that the mouse actually loses functionality. Recommendations on a mouse that is cheap and will last longer, ways to prevent this (that don't require me "checking in" on this employee), or maybe doctors that they can go to to get this checked out?
Edit: this mouse is used in an office setting. The picture was taken at my downstairs work bench after I replaced it with a new sacrifice.
