It didn't work

Hi Vincent, Please confirm that you have purchased the correct sensor for your base station. It's also possible that the base station is defective. Please contact us for assistance.
Great unit for the price.

Easy to set up and use, easy to see from a distance. A great unit for the price, I will buy another to replace another old one.

I did submit a very positive review. But this rating software keeps prompting me as though you aren't getting it. Must hang up. Sorry.

Better than original

Easy to install. Works well, totally satisfied !
