Sliding Glass Door Child Lock - OKEFAN 4 Pack Baby Safety Slide Window Locks for Kids Proof Patio Closet Doors No Drilling Tools Needed (Blue)

They work exactly as expected. I have 4 glass sliding doors, somehow different. They fit the newer doors better. The older doors they’re a little tight squeeze but it still works. I was hesitant because of the review that they *could not* get them off, but I put one too high on the tighter doors and with some hard work and floss, got it off in about 5 minutes and restuck it a little lower so I could push the door to close it if needed. I would rather it be that hard to get off so obviously the adhesive is awesome and my kid can’t get it off without the help of an adult. The look is sleek and not bad. I would make it smaller and more sleek if possible but I don’t think it could be any smaller and work this good. Really gives peace of mind with my 14 month old and all these doors leading to the pool.

So far its been holding up. One of the push in broke off 1st day but I still can use it and it works great.

Works easily to block both our slider and screen slider from being opened.

The first time I tried to install this, I followed the instructions exactly. Shortly after, the lock fell down in between my sliding doors and got stuck. My sliding door wouldnt close with how it was stuck, and I had to use a spatula from the kitchen to shimmy the lock out. I tried a second one and held it in place for triple the time suggested on the instructions, which has seemed to hold okay this time.

My 3-year-old figured out the locks on our sliding doors, so we needed something that would prevent her from opening the door but still make it easy for us to let the dogs out. This was the perfect solution and is very strong. Ive pulled the door open hard a couple of times on accident, and it hasnt budged!
