For myself the only flaw seem to be that the stock grill doesn't quite fit perfectly so I have to re-position it a bit sometimes before I add the herb. But when I dump out the spent bowl the screen just falls right out, it never gets dirty, and I can pick it up pretty much immediately to throw it back in and not get burnt. I think as residue builds up with use it may fit better but who knows.
If you bend the original screen ever so slightly, you can get it wedge in there nice and snug...and it stays in place. The original screens work great IMO.
