I had some from Aobobuy.
Big mistake!!
Seller is great (can recommend him), frame kinda OK-ish, but did not feel like quality.
Biggest problem is that you cannot really tell if a frame suits you unless you have tried it on. A rep may not have precisely the shape you want.
Also it proved difficult to get lenses. They were expensive, and the end result was lot of hassle, not a great saving and not a great result.
Don't do it.
