R-Go ToolsHE Break Ergonomic Mouse, For big hands, With Anti-RSI Software, Silent click, Bluetooth 5.0, Prevention mouse arm/tennis arm, Vertical ergo mouse for Windows/Mac/Linux, 5 buttons, Black

This may be the only truly left-handed wireless mouse with more than 2 buttons available in the entire world. I certainly searched long and hard. As a gamer, two buttons aren't enough - but to be honest, who still has to click "back" and "forward" buttons these days? We have just come to expect them on all but the cheapest mice.There were plenty of "ambidextrous" gaming mice (though few that were wireless). But they really aren't, other than the basic shape. Extra buttons are always puy on the left side of the mouse, under the thumb of right-handers and nowhere near the pinky of left-handers. They're just no use.And finally, I stumbled on this one. It's not a big brand - I couldn't find any reviews. So I took a chance. My other mouse is a wireless Evoluent upright mouse, which was extremely comfortable until I damaged my elbow and couldn't mouse with that hand any more. Evoluent no longer do a wireless left-hander. But this is wireless, it's left-handed it is SO comfortable - perhaps even more than the Evoluent. I could have cried when I started using it: at last, a decent mouse that would finally let me do the stuff (and play the games) that I used to! It's incredibly comfortable and ....just works.It doesn't have any drivers, nor are there any to download. It just uses built-in Windows ones. This is mildly irritating, as you can't (for example) set a mousewheel click to double-click*. And I would have preferred the "back" and "forward" buttons to be the other way around, just because that's what I'm used to. But set against the joy of a decent, comfortable mouse, these are tiny issues indeed.If you need a comfortable left-handed wireless mouse, you just found it.*If you want to set the wheelmouse to double-click when you press it, just google "Double click software". It's a tiny piece of free software for Windows that does that and nothing else.

Stopped working after 3 months, the drivers suddenly became unsupported and will not reinstall again with the standard drivers as per initial setup. There are no drivers available from the manufacturer site and this mouse is now useless. I found that the comfort level of using this mouse, for RSI, was slightly improved over a normal shaped mouse, however it still causes some pain after time at the computer. On reflection, after using this product, I would not recommend it and I find the software support for what is really a very typical office item, extremely poor. I will not buy from R-Go again.

This is definitely a good mouse for left-handed use. Your hand does not touch the surface/mouse mat at all, but rests on the top and thumb ledge of the mouse. I give it 4 rather than 5 stars because it feels rather light for my taste (and the price) and because it has a non-replaceable internal battery. It is charged with an old-style mini (not micro) USB cable. It claims 96 hours life on that, I have definitely had it work for 72.

I really love the mouse which immediately eased some problems in my left arm. However, I would have prefered a Bluetooth version which I was unable to find due to my modern laptop having only one USB port.Also, the charging port is USB Mini-B, which requires carrying an additional cable for mobile use...

Very impressed with this left handed mouse so far. It does take quite a bit of getting used to but the more I use it the more natural it feels. I think in the long term it must make a difference having your arms and wrist in a natural position because I have noticed already that my arm and neck feel more relaxed.
