Anyone using cheapo 'Riorand' red dots from Amazon?

[Paul-ish]

I'm looking for a cheap red dot for my GSG-16 when it shows up.
Just for plinking with .22... Not for hunting.
They seem to get decent reviews...
Just wondering if anyone here has personal experience with them?

I have a few on my .22’s, in my mind worth it for the price. I even had one crack because it fell over and it still holds zero.
