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!

My off-brand Anker "shark model" vertical mouse recently went out and I stumbled across this product while searching for a replacement. I was just going to buy another Anker model, but decided to give this one a try since the shape caught my attention and I am very happy and satisfied with my decision to buy this one over Anker.The mouse did take a little getting used to since the Anker models I use have more of a shark fin shape and fits in my hand differently. After my hand adjusted (took about 2 work days), I absolutely love the feel better than my Anker!! I loved it so much, I purchased another one since I have 2 software development jobs where I'm on the computer constantly.Pros:- Durable (has some weight to it & isn't just cheap plastic)- Responsive wireless dongle (I've had BT mice where the dongle was cheap and broke off inside of my laptop)- Very Ergonomic (the shape allows me to use my mouse for longer periods of time without feeling fatigue in my wrist, fingers, or neck/shoulder)- Smooth Movement (mouse glides on my mouse pad very smoothly and doesn't have tracking issues)- Fast / Responsive Scroll Wheel (wheel doesn't get stuck and glides nicely with finger; wheel glide speed translates to cursor on screen as expected)- Only takes 1 AA battery (my last off-brand Anker model went through 2 AAA batteries all the time)Cons:- I wish it was sized differently for portable / travel reasons since it is on the bulkier side when packing it in a backpack. The size may also be an issue for children or those with small hands- Mouse needs to be wiped down constantly or it will show your finger/hand prints (especially if your hands get sweaty, greasy, or has any residue from lotion, oil, etc.)- Can be slippery at times when transporting it (the material is slick so if you're very clusmy, you will absolutely drop this at some point)I HIGHLY recommend this mouse, especially if you prefer a vertical mouse over a traditional one!
