I absolutely love my mold with lids, the fact that I can put it on and leave it on my counter and forget about it is awesome. No ash so far either Love that I can look through the lid to check on my soap. The only down side was that the acrylic in one of them got a foggy, whitish film, that doesn't come off with washing but the company was quick to replace the lid.
I wish I would have invested in the premium mold sooner.
