Anker Vertical Ergonomic Optical USB Wired Mouse 1000 / 1600 DPI 5 Buttons Vertical Mouse

The size is really good. I am 6.2ft and I always search for big mouses - and this is really a very big one. My other mouse in the video is a tag basic mouse with random led. it is also a good fit. But this one is much bigger than it.For using: I have to take at least 1 week to get the hang of using a vertical mouse and it is a expected thing.And definitely not for pro games - this is ok..ish for games unless we get a lot lot lot used to with games.Edit: After months of use, The wrist is not paining now. But that palm is paining as I have to close my plamp/fingers to hold it. I guess only the evolution brand vertical mouses are only good as they are big and wide when holding does not require closing of the plan.

Works 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. Can't comment on the long term reliability, but if it keeps working as now for the next couple of years, I'm a happy customer.

It helps to reduce pain in your wrist.

I think this is the best vertical mouse at this cost on amazon India. feel clumsy handling this. I got used to it in few days and now I stopped using regular mouse. My wrist pain has reduced.

If anyone faces mouse shoulder (RSI) or discomfort in wrist or anything related to right side of your body just give this mouse a try. You may need one week to get adjusted but once you get adjusted this works like a charm

Great mouse! I had severe pain in my wrists, switched to this and now it's gone. Very glad I bought this mouse

Bulky na and uncomfortable to use

The change in wrist posture improves posture immediately.
