Vertical Ergonomic USB Mouse for left handed users - Optical Model - Mice with Ergonomic design - prevention against mouse arm tennis elbow - For Laptop Desktop PC Computer Macbook

I had previously bought this mouse in right handed version to help with sore joints in my hand namely knuckles, which im guessing is arthritis or RSI injury from years of mouse use, unfortunately my hand still tends to hurt albeit after a longer time than with a regular mouse so i have switched to a left handed version. the right handed mouse was by Anker and the left by CSL, virtually the same apart from the name and colour of the light strip. I nearly popped for the fancy Logitech mouse but could not justify the money wanted for it so I took a chance on these, build quality is great, you would not think it cost a tenner, everything is solid and comfortable, if I had to pick at something the rubber could be a bit stickier for grip, everything is easy to reach even with small hands, I cant comment on longevity as Ive only had it a week but it looks good so far. So I have both mice on my desktop but mainly use the left version although I am slower till i get used to it, would happily recommend it to any one that has trouble using a regular mouse.

I work all day every day with computers so I like to alternate between a mouse in my left hand and a mouse in my right hand to ease muscular skeletal issues. I use this one now for my left hand and it replaced a usb only version of the same mouse that I had used for a few years earlier, which unfortunately got eaten recently by my two young dogs. This mouse is great and I use it solely with the Bluetooth connection. I've probably already lost the usb dongle as it does not fit well into the slot in the bottom of the device and falls out too easily, but I have not had any issues using it with Bluetooth and it is nice not to have to bring a usb dongle thingy with me when out and about with it and my laptop. Just switch on and go.I liked that there was a button on the top to adjust how quickly it reacts, though I now notice from the mangled remains of the one that the dogs had largely eaten that it also had the same feature, as does the wired one that I use in my right hand at home.

It does what it says on the box.You will not regret buying this item.

What a difference this has made. I had pain in my left forearm and had been using a right handed mouse, in my left hand, for years, but I’m so glad I invested in this. Pain has gone and I adapted to using this mouse very quickly. I know us lefties are remarkably adaptable to our right handed environment, but nothing beats having the correctly designed equipment. I recommend.

Comfortable to use once you get used to it

I do work on CAD and have done for 30 years so I hate to think how many mouse clicks I've done! Finally thought I needed to get a better mouse to save my body. Being a lefty, it isn't that straightforward. This one gives a good neutral position and feels comfortable, given I have fairly large hands. The clicking action is good with the right amount of pressure and feedback. Tracking is good (on the wired version I got). Scrolling on the wheel is also good although I do prefer a rubber finish here that is more grippy. The matt black finish will also not show dirt and fingerprints. The only big downside is that panning on many programs is set to hold the mousewheel down and drag. The pressure needed to do this is definitely set too high and is annoying, hence 4 instead of 5 stars. That niggle aside this is an excellent purchase for the price.

Perfectly fine device at reasonable price. Which is something left-handers don't get to say often.So far so good. I have a wireless one (same device with different branding) but the main clicking button didn't always work. I imagine 2.4Ghz interference.from other devices.

The mouse is physically fine in terms of its hardware, but for whatever dodgy driver reason, the side buttons sometimes work and sometimes don't.I've tried emailing support about this, but they are completely unhelpful. I've shown my customer number etcetera here from amazon, but the moment they aren't obligated to help, they straight-up ghost. Literally just "does your mouse have a driver or is there a known solution to this problem."
