Easy install. Exactly we what we needed.

Amazing service, Product and all around

I wasn't sure what would work for my store. so i called and it was hard for me to explain, so i emailed them pictures of the store layout and was told the product that would be the right fit for my needs. It was a good price and i got it fast. i just used a 2 side Velcro to attach the sensor to the ceiling and it works perfect. i just wished i figured out how to change the sound because the way the instructions say don't work for some reason.

Excellent product.

Excellent product. We used velcro to mount it to the metal grid of a drop ceiling above the doorway entrance to our Frame Shop. Easy to set up. Although the directions are not explicit we figured it out. Works very well. We like the plain ding-dong tone. Threw away two systems that worked a short time. Both offered a multitude of long annoying sounds and songs. Worth the cost.
