Review: Great quality and protective - An excellent quality productsm. It has largely enhanced the security of our property by notifying us of any movement through the outer door.
Review: Low quality - I lost the desertcart gamble - it worked until it didn't. only lasted 3 months, during which i changed the battery twice. One day out of the blue, it just started going off and wouldn't stop until i took the battery out. Then everytime you install battery again, it either constantly alarms or if you get lucky, it waits till the door opens then constantly alarms till you take the battery out. Poor quality - that's what you get with the desertcart gamble - so cheap you don't bother to refund, but my money is still wasted.

### ⭐⭐⭐⭐⭐ Works well
*by A***A on 13 June 2023*

Purchased because can’t hear the front door open when in the kitchen, works well dozens of tunes to pick from and the minimum sound level is enough for me, maximum sound is very loud you would hear it in the back garden, only small issue was the battery tab was not present anywhere so not sure how long the battery has been activated for, strange size battery for the door contact as you can see in my photo so ordered a couple more, used screws ( my own ) rather than sticky pads for door contacts, fitted an working in 15 mins max, 5 ⭐️ from me…
