Addalock Original Portable Door Lock

I have used these before and have been looking for a new source as my previous source no longer carries them. Great product...easy to use and does the job perfectly.

Easy to install. The adhesive is holding very well (after a week or so. I’ve got one in a sliding door with a view and it isn’t very distracting to the eye. Most importantly, they keep my toddler from opening the doors.

This little helps me sleep better at night. I have on my patio doors and it works to keep me safe. Very easy to put on, just make sure it exactly where you want it because it adheres very quickly.

I've been using Burglabars for YEARS! Whether I was in an apartment rental or my own single-family home, these offer an extra layer of protection against break-ins! Just locking your sliding glass door isn't enough! These are easy to install, and easy to open and re-close. I put two on my large sliding glass doors, one close to the top and one close to the bottom. Two on each window, left and right side. Great if there are small children in the house as well. Look no further, this brand is the best!

We got these for 1st floor windows and sliding doors. The ones on the sliding doors were in a not temperature controlled full-sun location, so the glue detached in the heat of the summer sun. Also the glass is old enough to not be the double pained insulated doors. Had to go back to a stick in the track for security. Otherwise they work amazing in shaded or temperature controlled areas or double pained windows with the gas insulation between. The clear color gives a less obvious look to the windows making visibility a non-issue. And fit just right for opening windows and doors when disengaged.

Works great, sticks well, and keeps my toddler inside.

Lasted 2 months then the spring gave out. Great idea...cheep product!!!!!!

These work great home or apartment.

Al ser de plástico, creo que la seguridad te la dará al instalarlo lo más cerca de la otra puerta estando ambas bien cerradas y con seguro.

I've ordered these twice (one was a free replacement because I assumed the poor product was a fluke) and the adhesive does not live up to expectations. I put these on south facing windows in afternoon sunlight and after about six months, I could easily pluck them off my window.

Fell off the door within 48 hours of being installed.

Easy to put together and fits perfectly. Makes me feel a bit safer.

Not very sturdy,if you forget to unlock before you open they come off the door and will not stick again,not a good investment
