I get you use a mouse

Too small to cup your hand. Fell off of where it sits a few times and fell apart

Came free with a Irocks slim keyboard

Clicks very loudly

Works the way a mouse should. Inexpensive

None

It was free in a combo. It works

It's small. I think this is for a child's hand. Happy I didn't spend money on it

portable

small

Small works- mostly

I purchased two of these. Mouse wheel sucks. Scroll down a tiny bit, and the scroller starting jumping all over the place, up and down the page. Plugged in the 2nd mouse, same thing

Cheap ; Works

It has a tendency to move to the lower right of thee screen at high speeds if you move it slowly back you can see it is still moving to the lower right ; this is really annoying when you have a dual monitor setup
