iClever Ergonomic Wireless Mouse, TM209G 2.4G Vertical Ergonomic Optical Mouse with 3 Adjustable DPI 800/1200/1600 Levels 6 Buttons for Laptop, PC, Desktop, Computer, Notebook

I am so pleased with this mouse! It is very comfortable and very easy to just plug and play, no drivers or special settings needed. It has worked great out of the box for me on iMac, MacBook, and Chromebook.For those not familiar with the vertical/slanted mouse, it might take a tiny bit of getting used to, but it is such a better position for your wrist. There is much less strain on the wrist when it is functioning in the handshake position compared to the palm-down position of most mice. Just ask an occupational therapist about carpal tunnel/repetitive strain.My previous mouse was the Evoluent, which had been the ergonomic gold standard vertical mouse, very expensive at over 100 bucks, and consistently develops serious problems over time: the scroll wheel stops working (instead bouncing the page up and down in place when attempting to scroll), and then eventually the buttons start to double click every time you try to single click. I thought my first Evoluent mouse was a dud, but the second one eventually went the same way. This was so frustrating to have happen repeatedly with such an expensive mouse. I could not bear to spend money on a third, so I searched Amazon for a more economical replacement this time around.The iClever is even more comfortable to me than the Evoluent. I can easily reach the left-click with my index finger, even with my hand resting on the desk, whereas with the Evoluent, which is taller, I either had to reach my finger awkwardly or levitate my hand above the desk while mousing in order to reach more easily. I also like the angle between my fingers and thumb better with the iClever, not too wide or narrow. The mouse wakes my computer up easily with a shake. And if this one ever were to develop problems with clicking, scrolling, etc., at the price point of 20 bucks, it wouldn’t be so painful to have to replace. My only minor complaint with the iClever mouse is that the scroll wheel clicks loudly when scrolled, which can be an issue when I’m using my computer during a virtual meeting or phone call.I bought one iClever mouse and immediately liked it so much that I bought a second for my son. The second one came with an offer of an additional free mouse if I post a review, so that was a no-brainer to get one more mouse for my daughter. They were both able to adjust to using a vertical mouse quickly and easily. I love this mouse and am more than happy to share with everyone what a good replacement this is for the Evoluent!

I tried half a dozen of various fancy "ergonomic" mouses and they all felt extremely uncomfortable and caused a lot of tension in the hand and wrist. All, except this one. While I would still like it to be a little bigger, it has such a shape that I still can relax my hand even though the mouse is somewhat shorter than my hand.The mouse doesn't last too long (1-2 years), but it's not too bad either. Once my current mouse stops working, I'm going to buy it again (for the 4th time). There's just nothing else in the market that suits my hands.

Generally I like the mouse. I like the gap/separation of the thumb section from the rest of the mouse, unlike other ergonomic mice where the thumb is pinched much closer to the fingers, this mouse is comfortable to hold on to all day. The ergonomic design has reduced the wrist strain I used to experience with my old traditional mouse.There are two flaws to this mouse that I have come across so far. The first is easily remedied; the mouse is slippery. When you first get the mouse it has a velvety soft finish that is actually very slippery and it is hard to keep your hand in the proper position on it.. To keep my hand in the correct position I was squeezing the mouse harder and bracing the top of it with my thumb...This caused my thumb to get sore quickly and I couldn't use the mouse for more than an hour or two at a time because of the strain. I read another reviewer with the same problem and they found a great solution. I purchased some baseball bat or tennis racket tape from Walmart and lined the palm area and base of the mouse with the tape to make it less slippery (see attached images). This mostly solved the problem of my hand slipping down and off the mouse when using it.. I no longer get thumb strain from trying to hold onto the mouse when using it and have been able to use it for a full day without switching back to my old one.The second problem I've had with this mouse is not as easily fixed. The left mouse button does not click well at all. The mouse advertises to be a silent clicker, and it generally is very quiet, but unfortunately they traded the function of actually clicking for a softer quieter click (the click is so soft it almost doesn't click at all). I have a hard time getting the button to recognize that I am clicking.. It takes several tries to double click to open a file, often times highlighting the item or entering edit mode instead of opening it. Also, if I attempt to drag and drop anything I often lose the clicking contact and drop the item I am trying to drag, which is very annoying. I think a person with longer fingers will have an easier time clicking the buttons and getting it to recognize the click because the mouse buttons seem stiffer the closer to the palm section you get and easier to click the farter from it.Overall it is a good mouse that is comfortable and generally easy to use. Although, it does seem to be geared towards people with larger or longer hands that wont slip off or have trouble clicking the buttons. I do recommend it for the better ergonomic thumb placement compared to other mice. And even though the clicking issue is annoying it hasn't deterred me from using the mouse daily.
