Contour Unimouse | Award Winner Ergonomic mouse with Thumb support | Wired mouse | Vertical Mouse for Left-Handed | 35 to 70 degrees angle | 6 buttons + scroll | For Windows and Mac

I work in IT and use this mouse everywhere. I own 3 of them. I've got one at work, at home and have one for travel. Find it very comfortable.

There is not much option to left-hander mouse but it is good one, not feeling tired after a long time used, but it is easy to click wrong button, sometimes it will click middle button. But overall it is a good option for left hander

Whilst the adjustability is good, the amount of buttons and the variety of DPI settings welcome; the button placement, unless you have very short fingers, is very awkward to make good use of and can require a lot of hand movement.The scroll wheel requires considerably clawing-up of the hand to use with the intended grip on the mouse, and its shape and size precludes holding it from further back. The side buttons are very awkward to access even with the adjustable thumb-rest, necessitating a up-and-back motion rather than being accessible quickly by the thumb tip as on other mice.The placement of the sensitivity adjustment requires letting go of the mouse entirely or using a 2nd hand so is terrible for quickly changing DPI on the go as you might wish to if needing to swap from a relaxed to very fine control easily.This amounts to worse ergonomics than a typical fixed position upright mouse that's a third of the cost, defeating the purpose of its customisable grip.

The main "palm rest" angle is continuously adjustable, and works well, within it's range. I'd expected a greater range, but the actual range is useful.The thumb-rest is mounted on a stick, off of a ball-and-socket joint, off the palm rest. That works for fore/back/up/down positioning of the thumb rest, and the actual rest is on a 360 degree single plane pivot. All pretty good.They claim that the length of stick/distance from palm rest to thumb rest, is also adjustable. In my experience, that ain't so.Nonetheless.. It's pretty good. The issue with RSI is about unchanging, limited, range of joi t motion. I've found it easy, and effective, to change the angles, etc, with this mouse, and avoid RSI recurrence. So far.

I have the ambidextrous mouse (that looks like a penguin... can't remember the name right now but if you've been looking at ergonomic mouses you'll know the one I mean) I bought this because I like to use a mouse when I travel into the office for work and this is far less bulky. Unlike my other mouse this mouse you operate by using your wrists but it's very easy on the wrists it's highly adjustable meaning that you can get it to the shape and orientation that you require and change that throughout the day depending on whether you're standing sitting or just changing position in your chair. The only difficulty I had with the unit was getting a grip on it between my thumb and little finger it takes a little getting used to but once you have the hang of it it's great. For fellow left-handers this is a great unit just be careful that you look for the left-handed description and don't go off the picture. Build quality seems very sturdy my only fear is that over time all of the adjustable joints will loosen thereby reducing the efficacy of the unit. But I'm a month into using it and so far it's working adequately. I have the wired version because I'm wasn't keen on adding any more emfs into the electromagnetic soup that we bathe ourselves in. Interface with Mac is fine you may need a third party program to activate the middle button but other than that works with mac just great. One of the best mice I've used only time will tell on longevity / durability. Final point if you're looking to travel with this mouse then the hinge makes it susceptible to pressure. I bought a hard case Lykus HC-1420 Mini, it adds a little bulk to my work bag but it's a perfect fit and there's no way this mouse will get crushed with that.

Works fine and is comfortable to use

Excellent product. Makes work on computer easier. Very comfortable. Very good value for the money.

Having had acute RSI for over a year in my right wrist, then having physio therapy for 3-4 months, I can tell you that this mouse is a must buy for anyone who uses a mouse for at least 8 hours a day and suffers from wrist pain.What I like:- Ergonomic tilt allows for custom comfort, which is unique to this mouse, as-well as rest support for the thumb (also adjustable).- Sensitivity modes allow you to choose how fast or slow you want the cursor to move.- Build quality is good, doesn’t feel cheap.What I didn’t like:- The mouse ‘click’ sound is very loud for me, would of preferred a quieter click sound.- For the price, i would of expected something to feel a bit more premium in terms of materials used (feels like a large regular mouse).- Price is expensive.Bottom line:You can’t put a price on your health, this mouse is the best mouse I’ve used for relieving wrist pain, and for that, I would recommend this to anyone who suffers from RSI.
