## Customer Reviews

### ⭐⭐⭐⭐⭐ Loud alarm
*by D***H on June 5, 2022*

Easy to install loud alarm. Excellent product.

### ⭐⭐⭐⭐⭐ Great item
*by J***A on July 12, 2020*

Exactly what i was looking for. Quick shipment.

### ⭐⭐⭐ Enough To Pass Inspection
*by C***S on November 22, 2022*

The product is moderately well designed but not perfect. The overall fit & finish wasn’t bad. The weak link in this design is the mounting and magnet sensors which indicate the door is open. They weren’t very reliable on rougher surfaces and each of them came off within a few weeks. It was just enough to pass a city inspection to certify my pool so it served its purpose. If it was even remotely possible a small child’s life would depend on this system, I would not recommend it.
