EvoluentRight Handed Small Wireless Vertical Mouse, brown, VMOUS4WRSHY

Sadly this mouse is a step backwards from the VerticalMouse 4 for me, despite the reviews raving to the contrary. Firstly, it's not more comfortable than the VerticalMouse 4: it's actually less comfortable, at least for the bottom side of my hands and little fingers. Secondly, removing the middle click functionality from the wheel mouse (which is highly useful for opening new tabs from links or using in games) just doesn't make sense. I knew about that before purchasing, but I didn't realise how annoying the lack of this would be in practice.In short, you should stick with an earlier Evoluent (or other vertical) mouse that you've been happy with. In my case, this is definitely the VerticalMouse 4, as this is a comfortable mouse with all the expected button functionality. The new C mouse personally seems a step backwards to me or, given that it's not a direct replacement for the VerticalMouse 4, a weird step sideways. I'm not sure who has been asking for the middle click to be removed on mice, but if you're one of those people, please remember that you can easily disable functionality on Evoluent mice via the software, but you can't add missing functionality back in.

I am 56, and work in full-time administrative role requiring me to use a computer all day. I had been using a normal mouse for years, with no problems. However, I started getting stiffness in the middle joints in my fingers a few months ago. I went to the doctor, had a blood test to rule our rheumatoid arthritis (which it did) and the only conclusion was that I had RSI. I was advised by my colleague to book an appointment with the health person in HR at work. I did this, and my IT department provided me with an Evoluent mouse. To say I hated it at first is an understatement. I was thinking "No way will I ever get used to this!" However, somebody else at work who had been provided with the same mouse said that I needed to persevere, so I did. I had to admit, it caused no pain in my hand as the regular mouse had done, but I found it very hard to use accurately. I decided to initially keep both the Evoluent mouse and the regular mouse so I had a choice. I was slow with the Evoluent mouse so made a point of using it for just a part of each day. I did this for about two weeks, and gradually I found I was using the Evoluent mouse more and more, until one day I realised I hadn't used the regular mouse for a whole day. At that point, I gave the regular mouse back to IT. I have now fully adjusted and find the Evoluent mouse as easy to use as the regular mouse, but now I'm comfortable so it's finally become a win-win situation. My fingers no longer click or give me pain, and in the end, I actually found that when I was using my computer at home, I found I was missing my work Evoluent mouse. I only use my home laptop for personal use, so obviously I couldn't ask work for another Evoluent mouse for home. I therefore decided that to have the same comfort at home for £80 was well worth it, and I have therefore purchased the same mouse for myself to use at home, and I am very happy that I have done so. Please note this is a completely unbiased review, I'd never even heard of 'Evoluent' before getting the mouse at work.

Bought as a replacement for an older Evoluent 3. I tried the 4 but sent it back. I'm using it on Linux Mint so none of the fancy stuff works, nor is it needed. The extra width on the sculpted base is an improvement. What is greatly annoying me though, after a week of continuous use is, the noise the buttons make when you take your finger off them. They vibrate with a "twang" because they're too thin and flexible. This is due to the suction from your finger being released as you take your finger off the buttons. It occurs on the top and bottom buttons only. It's driving me nuts.When I first used it, I found the shiny plastic finish on the thumb rest sticky if you have any perspiration on your skin at all. I've got use to that now, but the noise gives the impression it's a cheap and nasty bit of kit. It's certainly not cheap!

I bought this in June 2014, it is very comfortable relieves traditional mouse based forearm pains I was getting, but the pinching action does cause other aches for a while until you adapt to the new 'pinching' posture, which is what happens when he primary mouse button is used.Click is very light action which I though was great... But there is a reliability trade-off, part longevity is very poor; thirteen months later and the primary mouse button double clicks every other click, I tried pushing the double click speed to the fastest setting, which reduced the number of double clicks to about every 5th or 6th click. I then uninstalled the v5.5 driver using Revo uninstaller and the Evoluent supplied uninstallation tool so only the native windows driver was left to see if it was a driver issue; still did it. So, I tried to clean it using an air duster (compressed air) still no fix…I tried to contact the seller but there is no way to do this via Amazon.co.uk, in fact it says to contact the manufacturer (even though that contravenes the UK Sales of Goods Act 2003 which states that the contract is with the seller and not the manufacturer). Any way I looked at the Evoluent website; they do not to offer any returns at all: to quote their Warranty section of their website "4. Refund is not available for products purchased through a reseller (not through our online store)." Which echoes what the Sales of Goods Act 2003 states (are you listening Amazon.co.uk?).So in summary this VERY expensive mouse will likely start to play up after ~1 year and there is no comeback on Amazon.co.uk...I recommend if you want to buy this check the refund policy of the reseller very carefully. I consider this is relatively low reliability device as I have a 2011 vintage MS Natural Laser Mouse 6000 that still works fine except for the battery cover broke (which was my fault) and that costed about a third of what this mouse did.So I have since bought an Anker 2.4G vertical mouse, much better as it is not so vertical so the hand is at ~60° rather than the rather extreme ~80° with the Evoluent product and it only costs £13!, it has the same number of buttons and the same three stage mouse speed/sensitivity settings and is wireless and the same easy grip finish and feels well made. (note that the wireless Evoluent is even more expensive than this one!). Also, the Anker mouse has slightly stiffer action buttons, more like those on the MS Natural Laser 6000 in action, but that is no bad thing as1) It is not so stiff that I cannot get used to it2) They are likely to last longer as are a more robust design3) I can buy three Anker mice for the price on one of these Evoluent ones and if I want cheaper, the wired one is £10...Also, I have experience of Anker warranties as I had a battery from them that had problems and they replaced them no quibble (18month warranty) did not even want me return it!Update 2017-08-05: Anker mouse replacement still going strong as are its buttons. Note can use X-Mouse Button Control to redefine button actions.

The product is an okay fit if you've got money to spare. The mouse is very upright and comfortable to hold without causing stress. However the positioning means that clicking using a normal technique moves the mouse as you click, creating inaccuracy. Instead you have to use a pinching movement between thumb and finger to keep the clicking accurate - not the biggest problem but takes getting used to.Beyond the decent ergonomics the mouse has a terrible sensor. It completely fails to track on my black gaming mouse mat. Oddly it tracks well enough on the wooden desk underneath. On the mouse mat it causes the pointer to stutter and jump. While it works on the desk the situation hardly inspires confidence.The build quality is okay, slightly cheap plastic feeling but robust enough.All of the issues with this product are relatively minor or can be worked around. If it were cheap then I would say performance is good given the price. However it's not a cheap product, is very much a pricey product and you would hope for better when spending so much.
