ProtoArc EM11 NL Ergonomic Mouse, Wireless Vertical Mouse Rechargeable Optical Mice with Multi-Device (Bluetooth + Bluetooth + USB Connection) for Computer, iPad, Mac, Windows, Black-US

This thing is really award winning good. And very cheap pricewise. I couldnt find a single ergonomic mouse with this quality and price. Pros: usb c charging , connectivity with 3 devices and very good material feel on the hands and great holding angle for the palm. Longevity will be seen over time

Does what it does at a good price

After using it for several days, I can confidently say this is one of the best upgrades I’ve made to my workspace. The ergonomic design truly makes a difference—my hand rests in a much more natural position, and I’ve noticed significantly less strain in my wrist and forearm. The buttons are responsive, the scrolling is smooth, and the grip remains comfortable even during long work sessions. The build quality feels solid and well-designed. It’s ideal for anyone who spends long hours at a computer or wants to prevent issues like wrist pain or carpal tunnel syndrome. Great value for the price. I would definitely buy it again.

Cómodo, la pila dura mucho, definitivamente gastar un poco más vale la pena en comparación con otros similares un poco más baratos

I recently purchased the EM11 NL Ergonomic Vertical Mouse on sale switching from a traditional mouse. It took about a week to fully adjust, but now I find it much more comfortable especially in terms of wrist and shoulder strain. The vertical design really promotes a more natural hand position. What I like: Ergonomic design: Much easier on the wrist and shoulder during long work sessions. Silent clicking: The soft-click buttons are quiet. Long battery life: Holds a charge well and can be used while charging via USB. Useful buttons: The two orange thumb buttons are great for forward/backward navigation and the DPI button on the side lets you adjust sensitivity on the fly. Bluetooth connection: Easy to pair and works reliably with no noticeable lag. Things to know: I recommend measuring your hand like the product listing suggests to make sure the mouse will fit your hand size The internal battery isn’t user-replaceable, but that’s common for rechargeable mice at this price point. Overall, this is a great mouse if you're looking to improve your desk ergonomics. I wasn’t sure at first but after getting used to it I can’t imagine going back to a regular mouse. Highly recommended.
