The pop-up drain cover is such an incredible improvement over our previous jacuzzi drain.  Larger, recesses nicely without an additional visible ring.  Hopefully the polished chrome finish will last.  It is not fully flush with the tub floor but the central location probably keeps it from being annoying.  Our plumber chose ABS over the provided PVC tubing.

Pros: Perfect fit for Reve tub
Cons: Not fully flush
