USB Wireless Optical Pen, Computer Stylus PC Parts Wireless 2.4G Mouse Pen‑Type Personalized Innovative Vertical USB Computer Stylus for PC Laptop Mac Notebook Left Right Handed (Red)

I was pleasantly surprised by this pen. Suffer with wrist issues with a traditional mouse and whilst your fingers can ache if pen is used for long period of times, it has helped minimise the wrist pain. My only complaints are batteries don't last very long and right hand button is difficult to use accurately. Can be used for simple games on PC too, which is a bonus

I bought this because I get hand pain from using a mouse. Thinking that holding a pen-like mouse might help, I struggled for a few days using this and must admit I don't use it all the time, but it sits on my desk and I do use it occasionally. it's a bit like going from an automatic to a manual car, forget what you did before and you'll probably find it easier to use!

It does what it says. But ergonomically it is horrid to old and operate. I basically went back to my wireless mouse.
