Mommy's Helper Lid-Lok Toilet Seat Safety Latch, White, 1-Pack

Short review: This is the best toilet seat lock I've tried (and I am ashamed to admit that we've tried a few now). It's easy to install, and secure.Details: We bought a few different toilet seat locks to keep our toddler's curiosity at bay, but a number of them require some form of modification to the seat itself, or the tank. While we weren't really against that, we were very concerned that the adhesives wouldn't hold if our kid really gave the seat a tug. (I'm not entirely sure this would hold up, either, but if he gets violent with it, the lock will open and not damage the rest of the toilet seat, anyway.)INSTALLATION: Pretty simple. You snap little spacers between what works as a sort of C-clamp around the inside of the toilet bowl, and this holds it in place. You can only uninstall it if you can get inside the toilet bowl in the first place, so the kid is powerless against it. One thing I will note is, I did run into an issue with one of our bowls, where not enough spacers were provided to make it as snug as I would have liked. However, it seemed reasonable enough that I didn't think it was going to come loose, and again, the mount is inside the bowl, so it's secure when latched, even if it's a little loose.EFFECTIVENESS: Well, I can say that it manages to bewilder and frustrate grown adults who have come to visit us, so I'm sure that it will cover the vast majority of children who use it. Once you know the trick (lifting up little levers on both sides of it simultaneously), it's very easy to open, so it hasn't bothered us in the slightest.Overall, all I can say is, we bought one, and liked it enough to buy another one for our other bathroom, and proceeded to rid ourselves of the other ones we've bought. This one's a keeper!

I had this installed for a while for the adults to get used to it, and only recently has my son been old enough to pull up. Within a month of him interacting with it, it was broken beyond repair. Here is what is wrong with this product:- The only thing holding it on the toilet is an L-shaped piece of plastic that's about 1/8" thick. My 11-month old son yanked on it a few times and it broke, sending part of it down the toilet into our septic system, and making this whole thing useless.- The system of spacers they have to make it fit a variety of toilets also make it stick out pretty far and not lock as securely if you have a thinner walled toilet.- There are a LOT of little crevices and ribs on this product, which means it gets gross fast and is hard to clean. You basically can't clean it without taking it off and submerging/rinsing the whole thing. And to take it off the toilet you have to try to pry open a little plastic lever *inside the bowl* where it is grossest. Also, the ratchet piece goes in once and then can't be completely removed, and so there is no way to completely sanitize it. There was black stuff growing in there that I tried everything to clean, but since you can't take it apart and the pieces fit closely together, it's a smelly mildew haven.The only pros: before it broke it did prevent the lid from coming up (and stymied a few adults who were visiting). A three-year-old figured it out immediately, however.I'm not going to order a replacement. I'm going to try a different product, as the design flaws are significant.

I looked into several toilet locks before ordering and I was disappointed that so many of the best-rated products involved more permanent installation. So I found this one and thought it was worth a try. Although I think my son will eventually figure this out (I've seen him try lifting one lever already- probably having seen us do it and he's a good imitator monkey), I'm hoping by then that he'll also understand not to play in the toilet. It takes some coordination to lift both levers at the same time. In fact, my husband and I have horribly enjoyed hearing our family go into the downstairs bathroom and have to call us to show them how to do it- all as they have to use the restroom. LOL! It is not permanent and doesn't seem to be leaving marks on the toilet or lid (of course, if you slammed it down really hard, you might get some marks under the toilet seat itself but we aren't the gentlest family and I don't see anything). If you are a larger person, you might feel the outer part of the arm against your thigh even when it is open, but it doesn't hurt and we've just pushed it towards the front more. I think this is a great option and works well.
