Not very practical

I went out and bought a pile of these based on the last reviewer, and will now be returning all of them. Hopefully they'll take back the one we opened too. Thank goodness I found them locally and didn't pay shipping charges to get these things.

Our entire house has lever style handles. My average sized 15 month old has no problem opening and closing these doors. 2 doors we really wanted him not to open were 1) the doors to the den, which have glass inserts just like the product photo shows. and 2) his bedroom door. I don't want him wandering the upstairs halls in the middle of the night.

First, we tried to install one on the glass insert doors to the den. The plastic lock thing is so big it didn't fit. We have a raised lip going around the glass insert part of the door, and there wasn't enough space between the door handle and this lip for the lock to install. So that was useless. Funny they show it installed on a french door, when it doesn't actually fit on a standard french door.

Next we tried it on his bedroom door. It installed just fine. You take the doorknob off, slide the plastic lock on, and reassemble your door. The problem? Well, the packaging doesn't tell you the limitations on how this thing operates.
So for us, we want to keep our child in his room. So we attach the lock to the outside of the door (in the hallway). To gain access to the room, you push the button and slide it over until it clicks on the other side. Then until you reset the lock back you have free access either way. But if you should ever happen to get caught on the other side of the closed door, you're really in a pickle!! There is ZERO access from the other side. My thought when buying this was that you would keep the child out as long as they weren't able to press a button. But not only do these lock a kid out, they can lock YOU out. If you maybe don't push the lock all the way to the other side and it slips back into the lock position. Or if you have an older kid who can operate the button they can easily lock you out. Then what do you do? Climb out a 3rd storey window? Kick your way through some drywall? Hopefully you don't have something on the stove cooking.

The instructions say you are supposed to install the lock on the side of the door you don't want the kid getting access to. So what if I don't want him getting into the pantry? I'm supposed to install the button on the inside of the pantry according to the instructions. So the only way to lock it would be from inside the pantry -- so obviously that doesn't work. But if you install the button on the outside someone could be permanently locked inside of their pantry. I can see an older sibling doing this to a younger one.

Someone needs to come up with a lever lock that is child resistant from both sides -- not just a complete denial of access from the other side.
I've seen that kidco makes a lever lock that they say allows access from both sides, but it just mounts with adhesive. There are optional screws which you'd probably want to do, but who wants to put screw holes in the middle of their door? If you are willing to screw into your door, it's just as effective to go buy a $0.99 latch and hook at the hardware store and install it at the top of the door. If you accidentally get locked in on the other side, you can still open the door enough to reach up and flick the hook open.

For our den's french door, we traded doorknobs with our ensuite bathroom door. So our den has a lock, and we put a key in the inside of the room just in case someone pushes & turns the button while we're in the den. Should we need to do this on more doors, we'll just order in another locking doorknob. We know it'll work, and it's not a giant white plastic eyesore on a dark brown door.
