Purchased as a gift for my brother in law a few months ago— he says it’s still working well!
Good magnet, sturdy, easy to install and use.

Not a good buy
Straight up, this thing is horrible. Doesn’t hold on to anything; especially if you add your phone, it just drops, damaging your screen. Don’t buy. Had no grip whatsoever or adjustability.
