VOXON Wireless Door and Window Alarm Sensor 2 Pack 2 Modes Magnetic Window Door Burglar Alarm with 100dB Loud for Kids Safety Home Shop Security

Having a disabled child who likes to open and escape from windows and doors, these have been a god send. Having the ability to switch between alarm, beep and no noise is really handy and this works well as a deterrent against escaping as well as alerting me to the unwanted opening of windows and doors. They’ve stuck in place really well, with clear instructions on how to fit them too. Total value for money and highly recommended

Top five of best purchase I’ve done in my life. They’re incredibly loud, even the chime is so loud I can hear it from the other side of the house. I could fit them in the window (which are not straight) and the tape looks strong enough.Easy to use and easy to stick to the door/window. The only “bad” thing is that there’s no light or way to know when the battery has run down.

First thing that needs mentioning is how loud these relatively small units are, the family heard me testing these behind closed doors 2 floors away. Very impressive. The 2 settings allow for a door chime sound (bing bong) and a piercing high pitched alarm (continuous). I purchased them primarily for our allotment where some miscreants have been attempting to break in to sheds and hope to at least put them on edge enough to leave. A small enclosure will be built to protect them from being tampered with. For the size and ease of install I couldn't be happier, 4 stars purely because the non standard batteries which may be easy to get hold of but I've not seen in general shops. I will try to get some before the originals run flat. (USB photo for size, not part of the kit). Highly recommended for the money.

Good quality, easy to install. I love that the batteries are loaded together in a line,unlike my previous alarm which go in at a slightly triangular and you end up trying to hold them in to get the cover back on as they keep popping out.

Work really well. Used as an alarm whilst away on holiday to place on the hotel door due to travelling with special needs child. Alarm is relatively loud and clear so great at alerting if the door is opened.

Excellent. I use in my shops door . Loud alert when someone enters. Great value .

Louder in open/close chime than on full alarm mode.

Great pic defo recommend
