Looking for wall-powered motion sensor switch

[sekker]

I want to put this in my garage, but leave the main overhead light circuit intact.

I have access to a wall socket, so don't want to use batteries.

This is one product from Amazon:

But there are a lot of negative reviews.

As this is for my wife's specific request, I thought I'd ask for real experts - MRFers!

Anyone happy with their motion sensor system and can make a recommendation?

TIA!
