SilverlineDoor Stop Security Alarm 1 x 9V Battery (898104)

I bought two of these door stop alarms primarily since the missus is somehow uncomfortable being alone in our second home abroad. So I ordered two of these ‘guards’ one for the front and back door each.It’s a pretty simple electronic product that has been around for decades - my parents used to have a very similar door stop alarm in the 1980’s, made of plastic and thin metal. But it works well. That is, it will sound the alarm. And it will perhaps cause some small additional obstacle to open a door. It’s reasonably sturdy. But somebody using force will still be able to open any door with such a stopper behind it. Either way, my wife feels much more at ease. And compared to investing 10x more for a half-decent alarm system I would say its good value for money. It does require a 9V battery.Now, since I had these lying around my daughter has put them to use to guard her bedroom. She is suffering quite a bit from a little sweets-snatcher (her younger brother). That tends to sneak into her bedroom, browse through her stuff and help himself to her sweets. The Very loud alarm already gave him a few scares during his frequent raids and might lead him to give up his despicable efforts.So except for the little looter, most are happy and pleased with this door stop alarm.

Put this behind my door and when I try to open the door it triggers the alarm.The alarm is very loud. Would be great behind a door in a hotel and if anybody tried to open it would alert you and scare them off with the sound.Does take 9v battery so make sure you have one of them.

Bought it for travel and hotel rooms. Depending on the doors sometime has not managed to fit. But works beautifully when it does, loud alarm if door opened. I didn’t know about the batteries it needed, so took it without them on holiday, which was an epic fail.

Bought this as we have had a few break ins recently, got it, tried it, and very impressed for the price. I posted a few comments on our local neighbour site, so far, quite a few people have now bought this, with over 100 comments, all of which were positive. Easy, cheap and would act as a great deterrent. Can't fault it, except might have been better supplied with battery for which I had to travel a couple of miles there and back.

A friend bought the same one that we used on holiday. When someone tried to enter our room the alarm went off! I think the people were genuinely confused about what door they were meant to access their room but this does really work and woke us up from our sleep (we are deep sleepers).

make sure guys u know it will fit i bought it without checking but im using it anyway, i think its good its loud! only thing is it should be cheaper than the price given as the quality feels very plastic! but its okay im using it ! hence the 4 star!! good job thanks

What a good idea. Feel much safer. I was going to get a lock chain but needed it fitted. £ 82. Decided this was a good alternative. Taking it on holiday too for the hotel door. I like that there's an alarm. Good price.

REALLY LOUD!! Works great and provided us with peace of mind when staying in a hotel room after a transatlantic flight when we thought we might not hear our kids getting up to "explore" if we were dead to the world. Tested many times and works perfectly. Has never gone off accidentally and fortunately has never been needed for real.Pros: Loud, and allows you to sleep peacefullyCons: Check the door gap first (not always possible). My experience is that even if the door has no gap the grippy bottom of the device will provide enough force to trigger
