ProtoArc Ergonomic Mouse, EM11 NL Bluetooth Rechargeable Wireless Vertical Mouse, 3 Multi-Device Connectivity for Computer/PC/Laptop, 2.4GHz Optical Mice for Windows, Mac OS, BlackClimatePartner certified

Even after a year of daily use, I'm giving this mouse 5 stars, despite the left-click button starting to wear out a bit.Before this, I had a Logitech MX Vertical, and I thought, “Well, it’s a premium mouse, so I won’t have any issues.” Surprisingly, it started malfunctioning after just 4 months.That experience made me realize that price doesn’t always guarantee durability. So I looked for a more affordable option on Amazon and found the ProtoArc vertical mouse. What really impressed me was that it offers both Bluetooth and USB connections, which is hard to find in this price range.I also noticed the click response, connection stability, and overall performance were just as good as the Logitech, but for less than $30. So I gave it a try, and honestly, I’ve been a very happy customer.Even though the left-click has started to weaken, I've used this mouse every single day: at home, at work, and while visiting customers. If you're using it only at home or in the office, it will probably last even longer than mine.I'm back here now to buy a second one after a full year of solid performance. Definitely worth it.

UPDATE BELOW: Have used a couple of Microsoft Scuplt mice, but they only last for 2-3 years and are too expensive to replace at that rate. Came to Amazon looking for something similar and saw this was promoted. Today is the first day I'm using it, and like most things about it, but I will say that the grip surface is very slick. The other item is the little "tail" that I believe is designed for the edge of the hand to rest on or against sticks out further than comfortable for me.These two things together make the mouse feel like it is pushing and slipping out of my grip. My natural grip is to put the edge of my hand on the desk right behind the tail, not riding on it. Then I do a lot of movement with just my fingers with the edge of my hand stationary.Maybe I hold a mouse incorrectly? I've been doing this for over 30 years, and never had write pain. I'll give this a couple of days to see if I can adapt, because I know each mouse brings a bit of a learning curve. Everything else about it seems really good in the first hour of use, so maybe I'll adapt to the tail.Ok, it's been a week and I'm a fan on this mouse. I do still wish the tail was a little shorter, but it's no big deal. It glides smoothly, the buttons are easy to manipulate, and the fact that it's rechargeable is perfect for me. I changed it from 3 to 5 stars.

It takes getting used too, but it comes with no drivers, as most mice don't really need them. I've had no problems with any mouse jitter or craziness when making precise mouse movements. Just takes getting used to as long as you aren't HAMMERING the mouse buttons making the entire mouse move. Take a few minutes adjusting mouse sensitivity in your OS, as well as it's built-in DPI settings, and make sure there's no interference with the 2.5ghz dongle, or if you have to many devices connected via Bluetooth (like audio.)I do wish the forward/back buttons near the thumb were a little bit lower, closer to my thumb. If you do have large hands (mine is 7.5") the mouse is still perfectly useable since I tend to use a claw-grip.Pros:No fussing with bloated apps or drivers, as it comes with no software.The USB-C port is conveniently placed so you can still use the mouse while it charges.It does have an on/off switch on the bottom.No RGB stuff (good for battery life)Supports two separate Bluetooth devices, plus it's own wireless dongle for a 3rd device.Cons:Does not use a laser sensorIt does not have a battery charge indication letting you know if it's fully charged or not, or even if it's getting a charge.The USB-C port on the mouse is only for power and battery recharging. So plugging in the USB to your PC does not connect the mouse to your computer. If you use your own USB cables that support data, the data won't be used.The provided USB cable is POWER ONLY, it has no data connections. Do not use it for other devices if you need a data connection.Very low DPI compared to most "gaming" mice but it does the job fine for gaming.

This mouse holds a charge for a very long time. I'm not even sure how long it can go without a recharge. I decided to charge it back up after a month of regular use, just in case it was low. It would be helpful if it came with an indicator that lets the user know when the mouse needs recharging before it's fully dead. As is, it's a guessing game.The shape of the mouse has alleviated some shoulder pain I was experiencing. On a whim I purchased this mouse wondering if it would help. It did - as well as getting a seat cushion to boost me up a little taller in my work chair.Simple to use and set up. No adapting time needed. Great product and it was on sale!

I fully charged this mouse on April 1st and made a note just to see how long it would last between charging. It lasted until July 24th!!! Extremely long battery life, great feel in the hand, has survived spills and drops and still works great! Love the medium setting for cursor speed and definitely worth the price. I use it 9hrs a day, 5 days a week and leave it on when not using and the full charge lasted two and a half months!!! (Almost wish I got a different color though, cause it’s going to last forever!)

I love the feel of the mouse. Smooth movement on screen and mousepad. Buttons are very quiet when clicking. Easy to use.The issue is have is the size. I have fairly wide and long hands and when I am using the mouse, the side/bottom of my hand near the wrist rubs on the table. I wish that portion of the mouse was a little longer. My fingers only go 3/4 of the way up the buttons. If I were to hold it like a normal mouse, my hand would slide down. It's like its too long on the top and not long enough on the bottom.Normally when I use a standard mouse, my fingers are closer to the top of the buttons.
