It is hard for the little ones to remove- but the little tab is hard for the big ones to remove also. Would not recommend

I like these because you cant see the outlet thru them which makes my toddlers even less interested lol. And they are difficult for them to remove, so it does the job.

So I used these to prevent dust from getting into outlets. Cheap enough, easy solution. They work great... HOWEVER, and this is a big one, they may work TOO well. I got these stuck in a few different outlets one being my APC UPS battery backup. I had to use a screwdriver (yes I unplugged it and didnt touch the contacts!) to pry it out. My advice is to just remove the ground plug portion (wire cutters or pliers twisting the post back and forth will do it). There is no loss of safety because it will still stay in the socket very well with just two prongs inserted. This is just a word of caution from experience, as it is much easier to remove without the ground prong and there will be no fear of it getting stuck in a receptacle.

Nice to have a little handle/grip when plugging and unplugging. Some are a little stiff to slide handle open. Sometimes hard to unplug, but could be the safety in the outlet itself.
