From a functional point of completely ok. However, there's nothing here because of high quality stainless steel (which was for me the reason to buy) determine. As another reviewer already announced is it in the cap to metallized plastic. It looks very fast very verranzt and is not nearly high. Cleaner of any kind, the material may already suffer at all. Enclosed now a few photos before he finally just wandered into the garbage. There are no soap residue, the material passes through normal use so on. Neither diverse detergent, the washer, nor a scourer can change that. One could polish him most :-)
