Wireless Left-Handed Vertical Ergonomic Mouse

This is a solid product and it is essential if you want to have good ergonomics and save yourself pain in the future. With how much we spend on computers nowadays, being smart about how you work is essential. It works perfectly after several months of use. Order it, you won't regret it. Oh, and just because you don't need it "yet", does not mean you don't need it now--if that makes sense :)

It came well packaged in a clamshell and was small enough to fit in my mailbox. Before I ordered this this my wrist hurt so much that I had reduced my computer use to just 10 minutes a day. As soon as I started using it my wrist pain went away. All of the buttons work as they are suppose to. It took about a day and a half to get used to. Having said that; I am small framed and have a small hand and my hand aches a little after prolonged use trying to wrap my hand around it as I think it is designed for a larger hand. I also have to use a wrist lift to raise my hand up enough to accommodate the height of the mouse for the same reason. I also feel that the area of contact where the thumb wraps around and the palm cups the mouse should be textured to prevent a clammy contact with the plastic. If this mouse had come just a little bit smaller I would have given it 5 stars.

This was a comfortable mouse that worked great for about a year. After that the scroll wheel quit working and rendered the mouse quite useless. Sure wish Logitech made a left-handed mouse!

This mouse is comfortable, the only problem is it is not working properly on a white surface. Maybe you would argue to use a mouse pad. But no one wants to carry a mouse pad from room to room in the office, LOL!

I have arthritis in my hands and between my job and my personal work, the constant mousing was causing my thumbs to lock up painfully. My hands were experiencing much wear and tear. The simple change to this mouse (of which I was skeptical) has made all the difference. Almost overnight, the painful locking stopped and in a short time, all of the soreness and stiffness in my hands went away. I wish I had tried it years ago. It's very comfortable and easy to use. I wouldn't do without one now.

I've used vertical mice in the past and found them great in terms of ergonomics, which is why I ordered this item when my old mouse died. Unfortunately it was dead on arrival: the wireless receiver wouldn't work on multiple PCs I tried it on. Troubleshooting diagnostics indicated the receiver wasn't functioning correctly. At least the return was hassle-free! 1 star for the product itself; 5 stars for the seller.

Has saved my right hand tremendously. Has helped with the pain on my right side, as I now use my left. Very worth the money.

We love this (especially lefty people).It's super ergonomic. My kids aren't left handed, but they use it (as I always have a lefty mouse). it fits well (I've small hands, but some of my kids have large hands).I'd buy it again and recommend it anytime.
