Product review (1 stars): This is really fake product! Don't waste your money.
This is really fake product from China! They are really bad. I bought 2 because I found they look good from the picture and the prices look reasonable. However, one of the two items was broken before I could install it on my pot cover. The second one didn't break immediately but was broken after 2 weeks. Also, the inside screw is not stainless and got rusted quickly.  I got rid of it after using 2 weeks.
