Wireless Portable Finger Handheld Laptop USB Mouse Mice Trackball Mouse with Laser Pointer for Wind

I have Essential Tremor, so regular mice are a problem. I've used a large track ball for years but it's too big to carry with my laptop, plus the connecting cord is a problem. This unit works great out of box; the laser is good for presentations. The unit gives much more flexability than a regular mouse or track ball since I can rest my hand comfortably while using it.

I've had it for a couple of weeks & love it. Hope it lasts.
