Perixx PERIPRO-801 Bluetooth Ergonomic Vertical Trackball Mouse

This trackball mouse has been a lifesaver. The vertical design keeps my hand in a natural position, and the thumb ball is precise. I can work for hours without any discomfort. It paired easily with my computer via Bluetooth. Worth every penny.

The vertical trackball design is very comfortable, but there's a learning curve. It took me a few days to become accurate with the thumb ball. Once I got the hang of it, I've been able to work pain-free. The build quality is good, and the battery life is decent.

This mouse is comfortable and works well, but the Bluetooth connection can be a bit finicky at times. It sometimes disconnects for a second, but reconnects quickly. The trackball is smooth, and I like the buttons. Overall, a good buy for the price.

I have small hands and this mouse fits perfectly. The vertical design is ergonomic and the trackball is easy to control. It's wireless and the battery lasts a long time. I've been using it for weeks and I love it.

I really wanted to like this mouse, but the thumb trackball just isn't my thing. I found it less precise than a traditional mouse, and my thumb got tired after a while. The build quality is decent, though. If you're new to trackballs, you might want to try one first.

This is a well-built trackball. The Bluetooth pairing was easy, and the battery life is good. The main issue is that the trackball can be a bit stiff at first, but it loosens up with use. Also, the scroll wheel is a bit stiff. Overall, a good product.

I've been using this trackball for a month now and I'm hooked. It's incredibly comfortable and accurate. The vertical design helps with wrist strain, and the thumb control is precise. The Bluetooth connection is stable, and the battery lasts for weeks. Highly recommended.

This trackball is comfortable and works well, but it's not without its flaws. The buttons are a bit mushy, and the trackball could be smoother. However, for the price, it's a great entry-level ergonomic mouse. I'd buy it again.
