Review on 👶 Enhanced Baby Electrical Safety: Babepai 38-Pack White Outlet Covers for Childproofing Electrical Outlets by David Caldwell

I bought these specifically to block air out of the 3 pin vents and they did a great job. They don't do it 100% perfectly - sometimes there's still some air coming out - but they do it with great success. Depending on the socket, they can be a bit tricky to insert and sometimes even trickier to remove, but I've used 36 of 38 of these and nothing has stuck either way so far. I took some sandpaper and sanded down the third pin on a few of them and that seemed to fix any insertion/removal issues. Overall, this product does what I need it to do satisfactorily: preventing air from escaping from the exhaust ports. I am satisfied and if I need more I will not hesitate to buy them.
