Dog security blocklock
Excellent Security Solution!I recently purchased the Guard Dog Security Blocklock and I’m extremely impressed. It’s compact, sturdy, and gives me real peace of mind when securing my belongings. The design is both smart and practical, and I love how easy it is to use just a simple click and it’s locked tight. It’s perfect for travel, gym lockers, or even around the house. Highly recommend for anyone looking for reliable and portable security!

Will get stopped by TSA
Works great just be prepared to get stopped by TSA. It definitely looks like a knife on the scanners.

Heavy Duty Door Security
This set of security block locks are very well made! The durability is amazing as is the level of security. I used this on a recent trip and my travel companions insisted on knowing where they could order theirs! The size and fit were perfect and I definitely felt safer! I’d highly recommend!

Very nice
Great product! It fits perfectly. It’s super fast and easy to put on and take off which means it is easy to open and close the door. It seems pretty sturdy. Obviously it probably won’t take a door kick or anything, bit it definitely helps with security. I wouldn’t change a thing about it. Even my mom (this is actually her account) who’s almost 80 can use it.

Pretty cool and useful product
Very cool product and valuable for the money and safety. Perfectly fits in traditional door hinges and is easy to use by simply inputting, and sliding tightly shut and locking it. Super functional with the safety it can provide and its lightweight so easy for travel or storage.

You keep on knocking, but you can’t come in
Travel alone and stayed in a hotel for the first time alone. Saw some pretty gnarly.stories online about women traveling alone and being prayed upon in hotels. So decided I wanted a little bit of security. Just the fact that it was on the door made me feel better, and I was able to sleep, which I don’t think would have went so well without that peace of mind. It was very easy to use, and I only had one TSA agent ask me what it was.
