Xiaomi Aqara gateway - need a secure/solid plug adapter

The plug adapter shipped with this gateway is terribly low-quality, and will not stay securely plugged into a US socket. What plug adapters are you using or can you recommend for reliable performance?

This works for me for years…I have 3.

I received this adapter this morning, and it fits very snugly and works well.

I use something like this, though I got the cheaper variant, it was around 12 euro.

Not a US one, but we use this one living in Belgium
