seenda Ergonomic Mouse Rechargeable, Vertical Wireless Mouse with Volume knob, Quiet clicks, 3 Device Connection (Bluetooth or USB), Optical Mice for Windows, PC/Mac- Purple

I own the Logitech version of this and needed to replace it. This one is BETTER. It’s got a cute color combo and it just feels sturdier or heftier. It works great and I have had no issues with the functionality of it. It’s comfortable for my hand and wrist and easy to set up. I’m a big fan.

Its a great ergonomic mouse and doesn't take very long to charge. It goes pretty far between charging times. You can use it while its charging too. The volume knob is really nice too! The colors are pretty. Highly recommend.

Zero learning curve with this mouse....idk how or why, but I was able to use it perfectly right away. The volume knob is a great feature, very pleased with that. I have a woman's medium hand and this mouse feels great, just the right size.

Love the angle, quite comfortable to use; do wish there was an option for a 90° vertical, but the given is still much better than alternatives. Clicks are soft and the volume knob is quite convenient (dont see on any other mice), I do bump it from time to time though. Scroll wheel leaves a lot to be desired; would pay more for a higher quality version, though insane bang for buck ($20 for mouse that mimics $150 logitech mouse design is amazing). Plug and play, easy to use no drivers needed (windows or linux). Functions like any other mouse!

I have carpel tunnel syndrome in both hands, and using a regular mouse hurts my hand. My friend told me to buy an ergonomic mouse, so I said sure. I've never used an ergonomic mouse before or one that is turned on the side like this one. However, I bought this one because of its high ratings. I love this mouse! It's comfortable, easy to use, and has high quality. The color is great too for all of you pink lovers.It comes with a USB cord to charge the mouse. All you need to do to charge it is to attach the cord to your mouse and to your laptop and let it charge. You can also use the mouse while charging it. I read someone else’s review. They said that if the mouse isn’t working or communicating for whatever reason, you can still use it with its USB cord, and the mouse still words. It looks like the company put a lot of thought into making this device, and it’s well worth the cost. I'm glad I bought this; my hands don't hurt anymore, and it’s super unique.When I started using this mouse, it took a little time to get used to using it on its side. I couldn’t fully wrap my hand around it, but I’m getting more used to it and it feels great on my hand.The thumb buttons are for going back to the previous page you were on, or going forward to the next page. The button on the very top of the mouse is for the volume. You can also press it down, but I honestly don’t remember what that part is for. The other side of it is the left and right clicks with the scroll wheel. There’s another button above the scroll wheel also called the DPI button that allows you to quickly adjust the mouse sensitivity. You will also find the charging port on the lower part of the mouse where it divides, and there are several other buttons and the USB receiver on under the mouse for connecting the mouse t to your computer. A user manual comes with this device that guides you through the setup.Shipping was on time and packaged nicely. I give this a 5/5 and recommend this product.

This is an excellent mouse. Although it appears to be slightly smaller than the others, it is the same size and fits large regular hands. The volume knob is fantastic. The controls' shape and position are well thought out. Best mouse I bought.

I ordered this mouse as a replacement when my other ergonomic mouse died and so far it works well! This one is rechargeable and hold a charge for a long time. The buttons work great, the only issue I’ve had is that my thumb accidentally hits the “back button” because the thumb space is smaller. The knob on top is a volume button on top, which is handy. The colors are super cute and the ergonomic part is nice since I use it all day at work.

I used Logitech MX Vertical for a few years, and I like it a lot, but recently it started to double-click (which apparently is a common issue), so I decided to get a new mouse.I tried the Logitech Lift and Lenovo Go, but they are too small for my hand (even though I have rather small hands).I like "bigger" and "steeper" mice, so finally, I ordered HP 920, Kensington Pro Fir Ergo Vertical, and seenda Ergonomic Mouse (purple).Here are my findings:Seenda:1. Pretty much the same size as Logitech MX Vertical and very comfortable (depends on hand size)2. The "Go Back" button under the thumb could be shaped or positioned differently because it may be accidentally clicked, but no big deal3. Lightweight and doesn't slip out while raising hand4. Sensor is aligned with the arm5. For the price ($25) quality is very goodConclusion: Overall, pretty good mouse and I'm keeping it.Hopefully the manufacturing process is good enough and the mouse will last at least three years.HP 9201. Terrible scrollbar2. Compared to Logitech, Seenda, and Kensington, I found it uncomfortable to hold, but maybe is ok for larger hand3. Easily slips out of hand if raised4. Sensor slightly unaligned with the armConclusion: Don't buy - too expensive. If you plan to spend around $90, then go with Logitech MX Vertical, or take risk with Seenda (not well known company)Kensington Pro Fir Ergo Vertical1. I like the shape a lot, even though it's a little smaller than seenda and Logitech MX Vertical.2. Sensor is unaligned with the arm by 10-20° (haven't found any option in Kensington software to adjust it)Conclusion: Even though it's verry comfortable to hold, it's almost unusable because of the sensor alignment. Let me explain. If I hold the mouse in comfortable position, then the sensor is twisted ~15° what makes vertical movement very frustrating, especially when precision is required (look at the attached picture)
