The plugs require superhuman strength to be inserted and removed from the socket. I don't know if it's a matter of quality, the fact that it has 4 slots, or because it's child-safe, but it's not practical at all unless you want to plug in 4 plugs and never remove them again...
I had read another review before buying them but I underestimated it. It wasn't emphatic enough!

Excellent for the money and sturdy construction that will last.

As for the difficulty in plugging and unplugging, which is the main negative in the comments, it is true that the positions/sockets of the power strip are stiffer/narrower than usual power strips. However, not to a problematic degree in my opinion.

It just requires two hands, one to hold the power strip and the other to insert the plug you want. If you try to do it with one hand, because it requires a bit of force, it shakes the power strip and is not convenient (and you might risk damaging the wall socket over time).

So it's not a matter of strength, but "technique." You get used to it easily; it will just seem awkward at first. Personally, I have it set up so that the 3 sockets are occupied by permanent devices, and I WANT them to be stable and never come out. Occasionally, when I plug something into the 4th socket, I do it carefully and that's it.

It does what it needs to do, solid construction. -1 star because it requires a lot of pressure to plug in the socket.

What a useless product this is.. After a while, the green plastics inside break and no breeze comes in... Stay away

It drives me crazy to plug and unplug a socket. It's like they're stuck with superglue. No kids or bodybuilders can unplug it! Especially if you try to connect a device while it's plugged into the wall socket, I think you'll break the socket. If you want it for a permanent connection, like a TV, TV box, etc., it will annoy you for 5 minutes and then it's fine. But if you plug and unplug, for example, your phone, it drives you crazy every time.

It does its job just fine. The plugging of the sockets on it is a bit difficult, but that's a good thing because of its baby proofness.
