I did the same cleaning procedure as for the door, but after 30mins the alarm fell off every time. Double sided sticky tape is used to easily adhere to inside of window. Advantages:- price point- Ease of install- Batteries included- High pitched noise putting off anyone being in that area. I've fitted them to all glassed opening doors and windows in my home.

EASY PEEZY! I have one stuck to a varnished door. For the price point and size it’s great. Without a full alarm system there isn’t many options that provide this type of sensor, so when this came along I was very intrigued.

I feel there were value for money as first off all they have the warning stickers thats a visual deterrent then if someone is bald enough to ignore the visual deterrent and they are loud enough to be heard outside the property. Like many, I'm not sure about the longevity of the supplied batteries. Nice to have option to turn sensitivity to high, low or off. In the very centre of the unit it has a spring mounted shock sensor making it quite sensitive.

These alarms do work, and are, in my opinion fit for purpose. I gave the area a wash and then a wipe with Isopropyl alcohol. To conclude a great unit perfect size and what’s more it doubles up as a warning sticker to people viewing it from the outside.

A little dab of super glue on each corner has kept it securely on, and it's relatively easy to pull off if required. They have two settings high and low they are not overly big so don't take up much window I put mine near one corner of the window. Good to have included batteries.

Small and really quick to install. The alarm stuck firmly and has sat solidly ever since. The alarm is very high pitches and makes it extremely uncomfortable to be in that room. Sensitivity seems to be just about right in my opinion.
