Geyes USB Mouse Jiggler, Undetectable Mouse Mover Device Has Two Swing Modes Jiggle and Multi-Track,Keeps for Computer/Laptop Awake, Driver-Free, Plug-Play，with Switch (Metal Black)

Excellent for its intended purpose. Plugged mine into my laptop, no setup required and it started doing its thing moving the cursor a pixel left and right. It’s not noticeable in that mode and does not affect how the mouse operates. I run some software on my PC that requires it not go to sleep or into screensaver mode. IT dept has those settings blocked and this was a way around that. Very pleased.

Keeps computer from shutting down and turning off.

It's two modes work as advertised. The jiggle mode is not noticeable when it's on, but works

Works for me

Fast shipping and it works like a charm.

Works great. I recommend it if you need something like this.

Locks up on return from sleep. Then you have to disconnect and reconnect it when you want to use it. Pilot light is a good idea, but recessed too deeply which makes it difficult to see from especially from above. Not recommended.

This keeps my computer from going i to sleep mode. I love it as a teacher. I don’t have to keep entering my password! Makes teaching and referring to my slides easy!
