Deadbolt Secure, Prevent Lock Bumping, Prevent Lock Picking for in-Swinging and Out-Swinging Doors, Install in Minutes, no Drilling (Nickel Plated)

This little guy works perfectly. I use it on my front door for security. Was super easy to install. Didnt even have to full unscrew the deadbolt, just enough to be able to squeeze this guy behind it. Very strong and durable and the hinge is strong enough that when you have it open it stays open. I will definitely buy more when I move into a bigger place. Its not in the way at all or inconvenient. The weight is very light and the size matched perfect with my deadbolt.

One of the maintenance lost their master keys at our complex and they won't replace everyone's locks. They swept the situation under the rug. This will work wonders during night time and you can sleep in peace knowing that even someone with a key cannot unlock the door. I would also suggest replace the default half inch screws to the plate and the dead lock with 4 inch exterior screws. And make sure that the plate side hits the king stud. That way if they were to kick the door, they dont have to just break the door casing, they have to fight with the screws into the studs as well. Another small guy was about to get through those red handled motel door travel locks. This works so much better Edit: works great. Easily able to remove during rental inspections and easily installable again. You would break the key before breaking this device.

easy to install works great.

Inconspicuous and works very well. Lock bumping is very common these days, with keys available on the internet for $12. To you thieves, ping away with your hammers and illegal keys. You might unlock the deadbolt but you won't be able to turn it. This cinches the turn knob. Its strong and tight.

Easy to install and works well.

It was easy to install. Seems like it would work if someone tried to break in. I will update on the durability in the future, since I have only been using it for a few months.

Worked perfectly. A must have for anyone needing extra security. Extremely pleased with how it's held up perfectly. I put on two doors In Less than 10 minutes and im an elderly woman who is not mechanically inclined. Gives you true peace of mind.

Great product

The product installs very easily, and is very effective. No worries about it self-closing unintentionally. When in the locked position, there is NO way to bypass the lock. The one problem occurs when not everyone is home and someone (by habit) flips it shut. For that reason, I'd recommend this for people who live alone in apartment buildings (where tradespeople (strangers) sometimes have to enter your unit), but not so much for bigger families.

Works great, but delivery to Canada is expensive, although it says "free shipping." It is not free, it is included in the price!

Very adaptable to thumbturn styles. Secures the deadbolt from being opened from outside. Easy installation.

The description is misleading. It did not fit my lock - not every lock is flat under the lock cover.
