Ordered a knife set made by Henkels with "Country of Origin" as Germany but they turned out to be made in Taiwan -- no reference to that in description. Returned it by calling to get RMA within allowed time. Six weeks later after multiple phone calls and emails telling me they issued refund -- still no refund. Had to call credit card co. to dispute charge. When you call Cookswarehouse number you get voicemail.
