Dual Disc Mouse Mover Jiggler, No Software, Random Movement, Patented, Designed, Engineered, Packaged in USA - Twister

This product is perfect! I like the different settings, and it's not too loud. There is a quiet buzzing noise when it's moving but it's not too bad. (I'm really sensitive to buzzing/vibrating noises, so if you aren't you probably won't even notice it.)

does what it says exactly

Bought 4 months ago, stopped working today.

Just plug it into a USB and this thing works like a charm! I love that it is American made, works exactly as advertised and designed, and is way better than the other options I tried. It has several speeds you can choose from, which is exactly what I wanted. It keeps the mouse moving so my computer does not go to sleep if I step away for a few minutes. By using two disks the mouse truly moves randomly, unlike single disk designs that often trap the mouse in a corner, where it fails to move. Dual disks also allows the mouse to travel across multiple screens very effectively, unlike single disk designs. It does make a low humming noise when the disks move, but I don't mind it. Otherwise I might forget to turn it off! I tried 3 different brands and kept this one... it wasn't even the most expensive out of the 3 I tried!

Works, but requires some tweaking if you want cursor to stay in a general area. My workplace recently forced the screensaver in one of our RDP applications so the mouse needs to stay in that window for it to work, by default it just shoves the mouse in one corner of the PC as it rotates too much and too often. Was able to tweak this by placing a quarter on the disk and placing the mouse so it's suspended on the edges, it only moves the cursor when the quarter passes by. The rotation does appear to change direction now and then so the cursor stays in same area now.
