content: I previous had a similar jar opener and have 2 places and wanted to keep one in one place and the other in another. This jar opener is an inferior product and the worse thing I ever purchased from Amazon(and I purchased numerous things)It doesn't grips all jars and it should have advised me of what it was made of.It looked various similar to the other one I own and I can't wait till I can find another jar opener like the other one so I can throw this one in the garbage.
