Be careful when it comes to mains voltage stuff and China. Often the products do not comply with European approval standards.
Doesn't ALWAYS mean the stuff is dangerous but I once ordered a number of mains plugs VERY cheap that needed to go in the back of my mains switches in the game room. They are the three pin type that go in devices, but male version this time.
The quality was SO bad that I couldn't even install any wires to them plus the construction was so poor that they were simply dangerous to use.
I sent them back to the seller (a company in the UK), got my money back and an apology and that they deleted them from their program (which they indeed did).
