Review on Double Layered Stainless Permanent Coffee Dripper by Janett Schweizer

I'm afraid I can't recommend this. It worked great at first, which is why I gave it two stars instead of one, but over time a fine, thick layer formed between the two layers and at some point the coffee hardly came out of the bag. I found a workaround using a propane torch to heat everything up enough to burn the stuck floor, but this solution is far from ideal.
