Child Proof Door Lock & Pinch Guard - For Door Knobs & Lever Handles - Easy to Install - No Tools or Tape Required - Baby Safety Door Lock For Kids - Very Portable - Great for Dogs & Cats

They seem complicated, but the execution is flawless and simple. These are the measures I use on all child locks and how the door monkey rates on them:Ease of installation: Instant.Ease of use: 3 years old and up when installed within reach.Damage to repair after use: non-existent.Effectiveness: 100% on interior doors with modern square jams. (May not work on older doors)Durability: remains to be seen.I would give extra stars for ingenuity if I could. These locks are the neatest thing since sliced bread. We use them to keep the baby out of an older child's room among other areas like bathrooms. It took only 2 minutes to explain to my 6 year old how to use it and he was thrilled that he could keep the baby out of his toys now. It is very easy to use so older kids have easy access to the places they need to go, but the baby shouldn't go, like bathrooms. I thought the baby would hate them, because he can see into the room, but not get in, but he accepted the locks and moved on. There is PEACE in our home once more! My only complaint has to be the price. Perhaps after they really catch on the manufacturers will give us a price break. I would buy them again though. In fact, I have already ordered a second batch. (And I can't wait till they get here! I have a few more doors to block,) I would like these to be easier for everyone to afford. I think they should be in every home with small children. They have the added benefit of being easily portable. Ours are going to grandmas house to limit the range of the baby while we visit. This is a very nice side benefit we have never experienced with any other child lock. If grandma wants to buy her own to use when babies visit, they install and uninstall easily, are pretty small and store flat. The house only needs to look baby proof when the baby is there.These are awesome for interior doors but not practical in all applications. I use metal flip lock door latches mounted up high for exterior doors and doors I want to remain closed. They are small white and cost about $2-3. It involves drilling holes into the door frame, which will have to be patched one day. They only work on doors that open out and have to be purposefully locked. These are very effective as long as we remember to lock them. They are also very durable, something that is necessary in our household. Examples are the front door, pantry and closets. For doors none of the children are supposed to get into for safety reasons, we have tried several things, and decided to just install standard household (exterior) keyed locks for security. This is for our medicine cabinet and other closets where dangerous items are stored. It was worth the extra expense to be certain that no one (children or others) would be able to get into those areas without our knowledge.UPDATE: By October 2014 only 2 of the 6 door monkeys I bought the end of 2013 and beginning of 2014 are still alive. I really wish they lasted better. We wish they would come up with a better version that has a better grip on the door and doesn't get cracked so easily. Either that, or make them much cheaper so it doesn't hurt so much when they get broken. This is an ingenious product, but it is not perfect. To the creators: You are the best! Can you do better? for cheaper?

Soo easy to install - just pop on and easily pop off. As long as you put it high enough for toddler not to reach, it’s super effective and also easy to open and close (even in the dark, from both sides of the door). I used it when visiting family since my toddler often wakes before me and likes to explore. Our family members house isn’t baby proofed and my kiddo is notorious for climbing over baby gates and I was worried about the stairs. This worked wonders, as the door doesn’t completely close so he didn’t feel “locked in” when he would accidentally close it during the day but kept him protected at night without me stressing about waking up when he did. We slept in the same room so it made it easier and safer when I would get up to use the restroom and was easy for me to use in the dark. It’s my new go-to for traveling! I love that it keeps the door open about 2 inches but doesn’t allow it to open any further. I think we are going to get them for the rooms in the house we don’t want our dogs or toddler in so that the doors don’t have to stay shut (better airflow). I love that these don’t have to be permanently attached like many other door mechanisms and take 30 seconds to read the installation instructions and 5 seconds to install. Well worth it for piece of mind knowing my kiddo was safe while we slept and whenever I got up in the night.

This is amazing. Double-use for us, as my oldest's door doesn't quite close all the way in the colder months here in Arizona, so this also keeps it from opening on its own...we've tried everything, and it wasn't really too much of a problem until his little baby brother became mobile; he's push the door open from the moment he learned to scoot down the hallway on his belly. The dogs would get in there too, but they learned much quicker than our baby has that brother's room is off-limits. My older son is 13 so there are things in there, within baby's reach, that baby needs to stay away from--small legos, pens and pencils, cords to Xbox, trash can with soda cans in it, all sorts of things that my oldest might not always be minded enough to put away--he can't even remember to close the door half the time, whether it latches completely or not! Well! I saw this and I thought, how genius. It's not permanent at all. No damage to the door or the jamb, not the wall. It's so simple and so effective. I'd love if the price were a little lower--seems kind of pricey for a couple of pieces of plastic, but it's SO THOUGHTFUL that it's worth it--it's not 'expensive,' it's just...you know...a piece of plastic that literally costs $16, seems like a bit much.But then you attach it and suddenly you can quit running to the hallway every time baby goes down it, and you're more so paying for that sigh of relief, anyway. I love that you can decide how low or high to put it, that it's removable at any time without any damage or tools, that it's easy to use, etc. I literally can't find a single fault in this. And I'm not kidding when I say that it's GENIUS. I was sitting here wondering if I needed to tie something around the damn doorknob and...wait, how would my son get out...etc, lol. I could imagine this wouldn't work for all doors, you'd have to have the right 'width' of a door. But for us, it worked out great! $16 little dollars well spent :)

This is a fantastic little gadget. My tornado of a niece is almost 7 and very smart, and this little guy still works to keep rooms off limits. The only downside is that it only works with certain frames. It needs a decent sized edge to grip or it's useless. Unfortunately the second one I bought had to go back for that reason - the frame is rounded and so it wouldn't catch.
