Anker 2.4G Wireless Vertical Ergonomic Optical Mouse for Work, Multi-Device Connectivity, 800/1200 /1600 DPI, 5 Buttons for Laptop, Desktop, PC, MacBook - BlackECOLOGOECOLOGO

Just got this so maybe it's new mouse smell but it's really a cool mouse! I normally use a Logitech left handed vertical mouse that costs $75-80, but have tendinitis so I'm forced to use a right hand mouse a bit.So my first impression, Anker has chosen a good product to put their stamp on. It's a great price at $30 and apparently (from other review) goes on sale as low as $15. Everyone should be using these vertical mice, they are so much better for your posture and tendons in your arm and hand.My mouse connected immediately even with me connecting the receiver/USB dongle to my KVM switch.So why is this mouse so cheap? First it doesn't have Bluetooth. I believe the more expensive vertical mice like my Logitech lefty mouse have a dongle but also work on Bluetooth, avoiding the need to use a USB slot if you don't have an extra.Also there's no app for this mouse to let me reconfigure the buttons to do different things. Having said that, there's also not the extra buttons I'd want to program, like a more expensive mouse would have.If you want these features you need the Logitech Lift, but it's 2-4x the price of this mouse, so if you have that kind of money, maybe get the Logitech.My final thing I'll say about this mouse and the most important: if you have small hands stay away from this mouse, I have rather large hands and can barely reach the buttons and scrollwheel. It's comfortable, but just barely.

*** UPDATED REVIEW ***ANKER customer support reached out directly to me after my negative review to rectify the situation and to get a better understanding of the problem. I explained and their support staff was very helpful and apologized for the issues that I was experiencing. They informed me that it was not normal behavior for this product and since it was still within its original manufacturer warranty period (18 months from date of purchase for mice at the time of this review) that ANKER would gladly send me a replacement. I received it after just a few days (May 6, 2023) and tested it out. It works like a charm and exactly as expected. The scroll wheel is functioning very smoothly when I scroll through long documents. (I cannot stress how annoying it was when trying to scroll through website code and the previous malfunctioning mouse was jumping around so erratically when scrolling!) Something else that I noticed when comparing my previous mouse to this one is that the scroll wheel is completely SILENT when I scroll. The other one, however, makes a noticeable "clicking" noise as the wheel rotates. I don't recall if it made that noise whenever I first received it (or if it progressed over time), but there's a definite difference between the two devices. If the previous mouse made that sound originally, I probably just assumed that it was designed that way to provide some sort of audible feedback to the person using it. But the new mouse is completely silent when scrolling. So, I'm mentioning this in case it is an indication of a fault or failing with similar devices.After the fantastic support from ANKER, I have updated this review and I am once again a happy customer! Thank you!**** ORIGINAL REVIEW ***I've always found Anker products to be great quality and a good value. I felt this way when I initially purchased this mouse less than a year ago and everything seemed good when I first started using it. It's a very similar design and feel to a previous model that I had by another manufacturer, and so I was quite happy with it and expected it to last just as long — if not longer — than its predecessor.However, I noticed that after a few months it seems that it has been draining batteries excessively. Even more annoyingly, the middle button mouse wheel has become increasingly erratic. It worked as expected at first, but now the scroll wheel is virtually unusable because it keeps jumping and glitching any document or web page that I'm viewing when trying to scroll. I keep a clean desktop and all of my peripherals, and it does not appear to be due to any dirt causing the malfunction, at least from what I could tell on a quick surface inspection. I'm hesitant to attempt opening the whole thing up and trying to clean it that way (even though that doesn't appear to be the problem), as it seems more like it's a problem with the device itself (the glitchiness and excessive battery drain).

I needed an ergonomic mouse but didn't want to foot the bill for an expensive one (or wait weeks for my employer to purchase one for me). This model was the right price and shipped free overnight (free with Prime membership). Within 2 days of use I noticed my wrist pain disappear and was very happy.I have small hands (5"L x 3-1/2"W) and this mouse fits perfectly. Good speed and reaction time for the work I do (lots of spreadsheets, graphs and emails). Button click and roller button noise levels are the same as any standard mouse. I don't use the forward/back buttons and sometimes I hit them with my thumb. Wish this feature could be turned off. Additionally, the device switch button is located near the thumb and I hit that often as well. The mouse has a smooth surface which feels nice but provides no grip so I find my thumb and hand sliding down. Due to the slipping I often find myself gripping the mouse with my thumb which causes pain after a long day of use.Overall, I am happy with the mouse but will probably add some grip material to keep my hand from slipping.PROS: easy to setup, smooth glide over desk pad surface, good fit for small hands, good reaction and speed.CONS: smooth surface allows hand to slip

Love it! Lightweight and comfortable to use. I don’t like that it requires batteries and can’t be recharged, but the battery life is impressive, it doesn’t drain them quickly. I’ve had it for about 1.5 months and haven’t had to replace the batteries yet. I mainly use it for gaming, and the extra buttons are very helpful. The wireless connection is perfect and never causes any issues.
