Review: Amazing for cheap safety - I have these on every door and window in my house. Work great, just remember to turn them off in the morning when you get up. Easy to install and the volume is heard all the way at the back of my garden and possibly more. Stick great to the door
Review: Warning ⚠️ very loud and effective - Very effective and value for money. Easy to setup too. I have installed 3 one the front door so I know who is coming and out I run a childcare business. One on French doors leading to the garden it startle the little when they try to access the garden without me. And one on the garden gate to for teenagers keep losing their house key and wanting the gate unlocked to sneak in not thinking of risks to little ones using an unlocked garden . Sadly British constant rain stopped it from sticking to the wooden gate it needs waterproof adhesive to be effective for outdoors.
