My doctor recommended a vertical mouse when I had carpal tunnel surgery since I spent a lot of time on computers. I am glad I listened. I originally purchased a Sharkk mouse, which I love, but I have to change batteries constantly. So far, I am in love with this mouse. It sits lower than my Sharkk does, but that actually better since I have smaller hands. I have been using it a week now and I haven't had to charge it yet! Its a WIN-WIN in my book. #RankBoosterReview #Sponsored #syynn https://www.amazon.com/Ergonomic-Vertical-Wireless-Rechargeable-Adjustable/dp/B07DW6Q3Z3
