They work as they should very easyWhen our son was old enough to start crawling, he, like most other babies, found some weird fascination with wall outlets. So, we knew it was time to get some outlet plugs to deter him from sticking anything in the outlets. After reading a few reviews, we decided to go with this product. They worked perfectly and are still working with him now at 17 months old.Pros:- You get 24 of them. For us, this set did the critical areas of the house. We always keep the doors closed to the other areas, so we haven't seen the need for a second set just yet.- The surface of them is flat. While some plugs offer a tab that can be pushed to easily pull them out, these are flat. We didn't realize at the time of purchase just how important this was. When my mom gave me a handful of the tabbed outlets, we put them in his play room and noticed him immediately figuring out how to pull them out. We were mortified that the safety device that was supposed to keep our child away from the outlets, drew him to them because he knew he could remove them. He hasn't figured out how to remove these flat faced plugs yet.- They're clear. The other plugs that my mom gave us was, according to her, white at one time. She's only had them for 2-3 years (she used them with my brother's children when watching them) and they have already yellowed pretty badly. With clear, 1.) you don't really see them, and 2.) you don't have to worry about them turning that ugly yellow color.Cons:- These plugs, as with 99% of all other plugs, can easily be placed in the mouth of a toddler. We've accidentally left a few laying about after vacuuming, to notice our son picking them up and trying to stick them in his mouth. The first time, he almost had the whole plug in his mouth. While I don't think he could have swallowed it, it could have certainly not been good had he got it stuck in his mouth. But, if you don't leave them laying around, this won't be an issue.All in all, these plugs were a great investment for us, especially given they were very affordable. If you're looking to baby proof your home, I would highly recommend these plugs as your first step!You can NEVER have too many of these available with little ones in the home. I have had these in my homes for years and these little handy plugs are perfect. They keep little hands out of the plugs. Just having them in the plug deters them from even trying to stick their hands in there. Easy in and a bit difficult to pull out of plug, which is exactly what you want. They are durable and strong plugs, I have purchased some in the past and they are a bit flimsy. NOT these. Included in this unit is a total of 24.Thank you.

Used primarily forprotecting outlets from debri and dirt in general when not in use.Works as expected.Product is as described.Seguridad y tranquilidad con los niñosI Think this is a must to have if there are infants or kids up to 7 years in your house.They are easy to use, and can safe your little ones from injures. I got them because my baby, and we put them as soon as he was born, hahahaha. (I know is to exaggerated) but we wanted to be ready. Now he is crawling and soon walking and oh yeah, we need them!! kids all ages are very curious (I am a teacher, I know it) that's why I dont think your outles are safe till kids really grow.Here's the deal: if you have new outlets (tight / nothing fits sloppy in) then buy these. If your outlets are old and loose....buy the safety 1st brand. And finally, if you're somewhere in between sloppy and tight, buy these.I have no complaints about these outlet covers other than I wish they weren't quite so wide. Some of my surge protectors are oriented with the outlets facing sideways so the covers overlap a bit. If I want to remove any I have to start with the one on the end.It isn't obvious at first, but the covers actually have a top and a bottom so make sure you plug them in the right way.Edit: Downgrading to 3 stars because I realized the plugs are too big to fit comfortably into one of my surge protectors. Disappointing.My energy assessment advised me to insulate my electrical outlets and when I checked them, there was a surprising amount of cold coming through them. I purchased these to cover unused outlets where cold air was coming in. I also added foam insulation to the outlets for another layer of insulation. Together they work well and increase the warmth of my home for very little money.The plugs are perfectly sized and sits firmly. I believe it's the best choice in terms of quality and cost.I received the box earlier today and noticed it came alone (My understanding: During order it was mentioned it comes with other orders). Upon receive the package was damaged on the bottom right corner and a single plug was damaged. Regardless, I really like this product and will order another pack. Not to mention I'll definitely recommended it to everyone!Es un producto para niños y creo funciona bien, mi problema fue querer usarlo para mí gato y encontró la forma de quitarlos XD, lo bueno es que le llaman la atención y juega con ellos en lugar de acercarse al enchufe, así que si cumple su cometido
