Super Grip Lock Deadbolt Strap Accessory and Portable Travel Lock

This is the best piece of mind for home invasion experience because it allows you to attach the device and you can visually tell that you need to tell somebody that you seen the device tampered with.

Works so well it broke the internal mechanisms of the lock with enough pressure applied to the door handle. Hotel engineering had to come to get us out of the room, but that’s the better than the alternative. Travels well, easy to use, no issues with Velcro (yet?). 5 stars.

This is a great concept! But could have been designed better. In the past, I've used duct tape to accomplish the same thing. I take a long strand of duct tape, roll it length-wise into a tubular shape with the sticky side out, then twist the duct tape into a rope like chord, and then strapping down the dead bolt to the door knob by wrapping it around in a loop, and being sure to tug down on the deadbolt in the locked position (see photos) I had even considered creating a similar product this one.But this product has a design flaw, at least with regards my particular dead bolt. My deadbolt is flush up against the door. This Super Grip needs to get behind the dead bolt in order for it to work at all. Since my dead bolt is flush up against the door, the dead bolt can't slip inside the 'pocket' that's part of the strap. I called the company, they recognized the design flaw and had no fix. I returned the product. They could have at least put a disclaimer on the product description.If they fix the design flaw, this would be an amazing product. Affordable, portable. If you have the proper dead bolt, buying this is a no-brain'er. If I had the proper dead-bolt or if this was designed differently, I would have bought one for the front door, one for the back door, and one for traveling.I'll just go back to using my duct tape. See the attached photo.

Hard to install otherwise it is great

SGL is a fantastic product, but it didn't work on 3 out of 4 doors I tried.1st door's deadbolt was too flush against the metal plate. I couldn't slip the SGL over the lever at all. SGL needs to be thinner.2nd door's deadbolt was too far from the doorknob. I get why they do it--the deadbolt is high enough that crooks trying to fish for the lever from under the door have to have a really long fishing gadget. But it means the SGL won't work because it's too short.3rd door's deadbolt lever was okay, but the angle was almost vertical, so the SGL didn't work too well. It didn't have enough leverage. Also, with the lever nearly vertical, the SGL needs to be longer.4th door worked perfectly. The lever was the old-school kind that looks like T-shaped handle, and it stuck out about 1cm from the door, so there was plenty of room for SGL to catch on and wrap around. It also locked at near-horizontal position, so the leverage was super strong. The doorknob was within reach.1 out of 4 is better than not having any protection, I suppose. I hope they improve the product to address the other issues, especially the flush-fitting lever that is so common at hotels. At least make it longer please!

I'm always looking for good security devices for hotels. I have a couple of different devices--door jams, alarms, security bar, etc.. I just bought the 2 piece lock that supposedly fits in the gap between the door and the jamb, but it would not work with the hotel door on this last trip. However, this little piece of velcro which weighs almost nothing and takes up no room in the suitcase is brilliant. We have some deadbolts at home, but the distance between the knob and lock is too great, but this worked perfectly on my hotel door. Most hotel doors have deadbolts fairly close to the knobs. I did have to play around with it at first trying to figure it out, but once I figured it out, I thought it was very secure. It would be extremely difficult to turn the deadbolt even from the inside. I don't see how it would be possible from the outside even with a key. Of course, there's always the issue of being in a fire and no one can get in; however, getting out would only take a second as the thing comes off easily just by peeling the velcro. I've had other devices that take longer, & I'm sure that the 2 piece thing would take longer.

Just tried it on my first trip and it’s easy to use wrapping around the door lock. I don’t know if it’s gonna work but it’s definitely easy to use and it makes sense.

This is a cheap and easy way to make sure no one can unlock your deadbolt from the outside. It holds under enough torque I'm certain it would break off the key or any lock pick someone might use. Easy to operate, easy to store. This unit is a replacement for the one we had on the door for nearly 10 years, and we could have used the existing one longer if we wanted. The new one is exactly like the previous strap.
