These bands don't fit as neatly on the cups as cork, they still have heat transfer since they are a bit thin. Better than nothing. The texture of silicone rubber is always nice, and it doesn't add much to the circumference like cork, but I prefer natural material.

I really wanted a cork replacement. When I could not find one I settled for silicone. The cork were so expensive it was about the same to buy a whole new glass. Next time, that's what I'll do.

Really like the silicone feel. Prefer this band to the cork.

Good replacement for a broken Cork band, but hard to get off when wet and also not as heat absorbent as the cork bands.
