Great when it works. didn't last long.
Great range and loud enough to annoy you if you turn it up high, however, it's now stopped working after about 6 months. It appears to be the receiver end (the Plug in) that has failed. It randomly changes tunes and intermittently works even though I've replaced the battery with a Duracel.I would avoid as there are too many instances in the review section the same as this.

Entrance alarm
Bought 2 for front and back door. Easy to install and different sounds to choose from

Works a beaut
Installed it on our front door when we have the builders working on our house so that we know when people are coming and going into the house. Works as described and has been working for the last 4 months with avg 5-6 opening/closing of the door per day. The receiver was attached to the middle of the house and it's loud enough for the household to hear even with the low volume. Unfortunately, we lost the second pair of the door sensor before we could install it at our back door.

Installed 7 months, no issues, great product.
I use these on two internal doors, rather than front/back door. Work as described and only had to change one of the batteries once recently after 6 months in use. Batteries are cheap enough to buy. You could even fit these to cupboards etc if you really wanted too. But remember you would have to turn the main unit off if you wanted to disabled the chime. Would recommend.
