Unsanitary
Works great, but over time mold will seep into the pores of the bamboo. I've tried scrubbing with a hard sponge, using abrasive powder meant of nonstick pans, soaking in bleach water, and boiling/steaming. As pictured, none of my attempts could get the mold off. Their is also a small crack that is starting to form at the lop of the ring.
