Most customers were happy the mouse was comfortable, affordable, and helped with carpel tunnel. Some customers noticed they needed to adjust their seating angle to be most comfortable.
Summarized ReviewFairly comfortable (though too light, which makes it tend to tip), relieves worst of carpel tunnel, decent texture and scrolling when new.
Ian D · from AmazonI've had my mouse for a little over a week now and I absolutely love it. Over the past few years I've started to pay close attention to how continual computer use is effecting my hands, wrists, and posture. I wasn't in any pain before purchasing the mouse, but a normal mouse forced my hand into an unnatural position. This mouse allows me to keep a much more neutral hand position while limiting wrist bending.
Justin W · from AmazonWorks as expected. Takes a couple of hours to get used to if you are a regular mouse user, but then it feels seamless. Does serve the purpose of correcting your hand posture and avoid nerve pain in the wrist/finger/thumb. The overall build quality looks good. The DPI switch provides toggle between 2 cursor speeds.
Dhawal K · from AmazonI bought this mouse and the Amazon Basics padded mouse pad. After a full day of work, I can confirm that both of those products help big time. I never really paid attention to the positioning of my arm, wrist, and hand when using a traditional mouse. After switching to the vertical mouse, I noticed that the traditional mouse was causing me to bend my wrist and arm in an unnatural manner.
Culture J · from AmazonEveryday: Just yes. Especially considering the value. It is both affordable as an ergonomic mouse and comfortable. You may need to make adjustments to your seating angle as the tendency is for this mouse to be most comfortable when your forearm is almost flat on the desk surface.
