I like the way the pots look, i used the square frying pan and put a little oil in it. Literally a cap full, and now the pot is stained and the stains won't come out.
All of the other pots work pretty well, they're easy to clean. The only thing I don't like is that the handles are not heat resistant.  Other than that, they've been alright. So my suggestion is not to put any oil in the pan, it doesn't work out too well.
