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, Black

after 9 months of using this mouse, it is absolutely 5. After you adapt to use it (use rough mouse pad) you can see how seamless it is especially when transferring signal from one device to another. Battery is also amazing and material and quality are superb. Above all of that, the vertical configuration helped in relaxing my hand and reducing the pain.

Good thing to know that is its battery life is too long

Excellent

Feel and design is very good and has a good premium matte finish on top. Easy to connect, supports Bluetooth and can connect to multiple devices. Device toggle should have be above for quick access. The normal usb dongle is kinda little lose fit and feels insecure and might fall off easily.

Very comfortable and the feel is nice (it is rubber and not plastic unlike other ergonomic mouses)

I have been using this mouse for a while now .. and I have recharged it only once since I purchased it .. and its keeps going on and on .. no spending on batteries any more ... and worth to comment .. the mouse had fallen many times to floor from table and nothing breaks it .. some special kind of texture .. body .. so strong I can surely say .. its worth the money

I bought it but decided to return it. Its good and works well but i dont think its comfortable for long time use and only suitable for small hands

It took me some time to get used to this mouse, but now that I’ve been using it for some time, I really like it

This ProtoArc ergonomic vertical mouse is such a good buy. It has two connectivity modes (USB-A and Bluetooth) which work great out of the box with no need for any software installations. With the Bluetooth connection, you can connect up to two devices. While you cannot use them simultaneously, you can easily switch between them with the click of a button. Other features include: 1. Power: It is powered through USB-C, and you will find yourself recharging only about every three to six months depending on your use. It charges quickly. 2. Navigation: It has two side buttons for moving forward or back on a webpage, although there is no built-in native app to edit these buttons. Overall, it is great for your hand and recommended for people with big hands.

Mouse de gran calidad en los materiales se siente como un mouse de arriba de $1,000. Los clicks casi no se sienten y ni se escuchan el confort en la mano es estupendo la verdad quede encantado con el

I absolutely love this mouse. I bought the ProtoArc ergonomic vertical mouse to help reduce wrist strain, and it has made a huge difference. It feels very natural to hold and keeps my hand in a much more comfortable position compared to a traditional mouse. The design is sleek, lightweight, and fits nicely in my hand. The buttons are responsive, the scroll wheel is smooth, and the wireless connection has been reliable with no lag or dropouts. It did take a day or two to get used to the vertical design, but once I adjusted, I found it far more comfortable for long hours of work. I use my computer for extended periods, and this mouse has significantly reduced the discomfort I was experiencing in my wrist and forearm. Highly recommend this mouse to anyone looking for a comfortable, ergonomic alternative to a standard mouse. Great value for money and one of the best office upgrades I’ve made.

I bought this mouse at the same time as an ergonomic mouse pad because I was having so much elbow and wrist discomfort while working that I was starting to wonder how I was going to get through my workday. I can't say which one deserves more of the credit since I started using them together, but WOW. Within a day, I noticed a huge difference in how my arm and wrist felt while working. This mouse is incredibly comfortable. The vertical design puts my hand and wrist in a much more natural position than my traditional mouse. The instructions say to allow one to two weeks to adjust to using a vertical mouse, but honestly, I was comfortable with it on the first day. My hands are about average size, and the mouse fits my hand perfectly. I also love that it can connect to three devices. I currently have mine connected to two different laptops, and pairing was almost instantaneous. There was really nothing to it. I was a little concerned about using Bluetooth because one of my laptops has a tendency to lose its connection with other Bluetooth devices, but I haven't had any connection issues with this mouse. The battery life has been impressive too. I've been using it for about a month, have only charged it once - when it first arrived, and it's still going. It's your typical black mouse, but it feels durable and well made. My one annoyance is the scroll wheel. I sometimes inadvertently press down on it while scrolling, which activates auto scroll. The auto scroll isn't particularly smooth either, so I'd rather not activate it at all. I'm getting better about not accidentally pressing the wheel, but it still happens occasionally. Paired with my ergonomic mouse pad, this has made working at my computer so much more comfortable. The comfort alone made the switch worthwhile for me, and the battery life, easy pairing, and ability to use it with multiple computers are bonuses I actually use.

Outstanding experience and price
