Effective & economical, easy to use solution!
Got this for set of French doors to the office to keep the cat out. Cat busts thru the doors to get to things to chew on and quickly broke the plastic bar type safety lock, which was much harder to use. These work excellent; loops are adjustable and it's easy open with one hand, easy enough to lock. Having two, we have one on the outside and inside of the doors, to easily lock when we're in the office. Turned out to be a very economical and effective, hassle free safety lock for double doors (or handles).

A must for parents !
These work so great! The decoy button is deceiving so my toddler can’t figure out how to open it. My son gets into everything so i needed something sturdy and no easy to figure out and these do just the job! Great quality and can pretty much work with many different handles since they are adjustable. I ended up purchasing more for other places in my home.

A MUST HAVE FOR TODDLER PARENTS!! *Read Full Review For Important Details!*
I have a three year old who is a SNACK MONSTER! She will even climb, if necessary, to gain access to any cabinet she believes might have food/snacks/candy etc. These locks are fully adjustable with long bands that can be completely released from the loop and inner-locking mechanism. There are 2 small, hidden, pressure-point tabs on the back of each half of the lock. They are sturdy and require strong counter-pressure to loosen (or fully release) each band. The band adjustment tabs are 100% hidden from access once both parts of the lock are in place. Once the bands are re-inserted, and both halves of the lock are secured together, I highly recommend the user to tighten the bands as tight as necessary. There is a bit of learning curve to using these; but they aren't difficult to use and figuring out what works best for you should happen quickly! IT IS IMPORTANT FOR ME TO MENTION: **My toddler WAS able to figure out that she could slip the bands over knobs, essentially removing the entire lock, but that was only IF the band(s) were too loose!** This specific feature (the functionality of the fully adjustable bands) made it possible to place a lock on our refrigerator door handles [which fully connect to the fridge doors at both ends of handle]. These locks have helped us safely secure the fridge as well as the pantry, AND the medicine cabinet... just in case! OTHER NOTES: **My -almost- 8year old IS strong enough to release/remove the lock [but she knows what to stay out of] so I don't suggest these for children older than maybe 5 or 6yrs old or for children with advanced hand-strength/dexterity. (I do not recommend demonstrating how to disengage the lock to anyone that doesn't NEED to know how) **For those who may have cabinets with "cup-pulls" (instead of knobs or handles) I would HIGHLY suggest the Safety 1st hidden, magnetic, lock with the magnet key. The locking mechanisms are installed inside the cabinet. They are a sleeker option if you don't want something that calls attention to itself! The magnetic keys that disengage those particular locks are SUPER strong. That feature, generally, prevents the use of regular fridge magnets as they are not typically strong enough to engage through most materials that you would apply the lock to. Overall, Safety 1st has been my tried and true, GO-TO, brand for various baby need for MANY years!

Love these and I would buy them again but…
I do love these locks. My son who is almost 4 years old has still not figured out how to open these locks. Though he does know how to close them. We have had this kind from this brand since he was an infant. I had to buy more now that we have another baby in the house who’s even more curious about the cabinets and putting stuff in his mouth. It really helps ease my mind that the locks won’t be left open with my toddler opening them. They are really sturdy. Like I said we have had some for 4 years and they are still going strong. The fake button makes all the difference in the world with child proofing. My4 year old has figured out the majority of the baby proofing that we have used except for these. They are easy for an adult to open but tricky for the kids who don’t understand how they work. They are easy to install. There are a couple of things though I do dislike though in an effort to keep my baby safe it I can deal with the issues. One problem is if you tighten them too tight the lock won’t unlock. It has to be enough to prevent opening but not too much or you’ll have to break the lock open with a screwdriver. Removing the screws on the back of it doesn’t do much for you. You’ll have to pry it apart with possible breakage. We had that with one of our old ones and I had it happen with one in this new pack too. It’s a hard balance to achieve and if you don’t know that you’ll make the mistake. Problem number two is when tightened enough to prevent the cabinets from opening the lock sticks out. That means the straps are in the way and you’ll bump your legs on them. I tried this time to cut the straps shorter after they were properly adjusted. I didn’t want to cut too close at first because it wanted to be able to pull it through again if I needed to remove it. But what ended up happening was both my husband and my toddler cut themselves on the straps. So if you leave the straps as is you’ll catch yourself on them and if you cut themselves shorter your cut/scratch yourself. Not ideal. Since I had already done it and I don’t want that to happen I cut them down to the very edge now. So if they get messed up I probably won’t be able to put them back on ver well but at least we have less of a chance of getting scratched by them. So while not easily removed and they stick out from the cabinets, they do their job of keeping the cabinets locked.

DO NOT BUY
DO NOT BUY!!! I wish I could give it ZERO stars. These locks are impossible to use. I bought the 4 pack and one out of the four didn’t even work. Okay no big deal I have 3 left. The one I put on my kitchen cabinet worked for 24hrs then it would not unlock at all. No matter how hard I squeezed the unlock mechanism it refused to open. It literally locked ME out of my cleaning cabinet. I had to resort to scissors to cut it off the cabinet in order to get to my stuff. This caused me to scratch the door because of the scissors. So unless you want to be locked out of your stuff or have to damage your cabinets just to remove this lock avoid it at all costs.

Keeps Out the Dummies

Son muy fáciles de usar y sí cumplen perfectamente con la función de mantener cerradas las alacenas. Tiene un botón al frente para mantener entretenido al bebé, pero se abren aparentando arriba y abajo al mismo tiempo, súper sencillo. Me gustaron mucho.

Works great. My toddler can't figure these out. I was having difficulty finding a solution for my cabinets that would not damage the paint. These work great and are very easy to adjust.
