I was nervous about buying a brand I'd never heard of but I can't tell you how much I love my purple VicTsing wireless mouse. So easy to set up and fits my hand perfectly. It comes with batteries, a little wireless chip for my laptop, it and works awesome! I would buy this again in a heartbeat!

Arrived quicklyGreat product and as describedNo issues

Very nice mouse for my laptop.

Nice fit to hand. Smooth mechanics. Color is beautiful. Never had the front/back button next to thumb before, as I teach my hand to use it I find I really like it.

My physical therapist recommended a vertical mouse to help with my tennis elbow pain, so I gave this one a try. The vertical orientation did seem to help my elbow pain a bit. For working in documents and emails it's not too bad, but in a CAD drafting context I found it difficult to be as quick and precise with it as with my regular mouse. After a few weeks of daily use, the scroll wheel has developed a high pitched squeak that's like nails on a chalkboard after awhile. And I found that to click the mouse, my thumb needs to be pushing back against the force of my clicking finger which over time has given me significant pain in my thumb joint. I'm back to my regular old mouse now, and disappointed that I can't return this one.

The mouse works, but I was disappointed by the design flaws. This mouse does not cover the USB hole. It's out there to collect dirt or dust and will have to be cleaned. Normally the USB port within the mouse is held under the battery cover. This prevents a dirt collection problem.The battery cover also has a slot in it, as well as a hole around the laser. These holes allow dirt or dust to easily coat the battery and the inside of the mouse.Because of the unnecessary holes in the bottom of the mouse that could fill the mouse and battery with dirt and dust, I would not recommend this product. I've bought many mice for $10-15 and have never had this issue. You can find similarly priced products that are designed better.

The mouse worked great for two days then the dongle stopped working. I contacted VicTsing customer service today and have yet to hear back. If they help me out I'll change the review since it was a nice mouse for the price, but be cautious since this is a cheaper mouse.EDIT: I changed my review from 2 stars to 1. After my first mouse was defective, I decided to buy another because I figured it would work, even though I still haven't heard anything from customer service. This mouse didn't work out of the box. I'll be contacting Amazon now since VicTsing does not respond via their support email. I won't be buying a VicTsing again.
