It's a bit too soon to provide a review since they only arrived last week and I've used 2 pieces one time only.  I did not use either of them "dry", so I can't yet comment on whether or not food will slide right off.  I can say that I am displeased with the colander, which I had assumed fit inside the soup/pasta pot, but it doesn't.  It's just a cheap colander, of which I already have 4 in different sizes.  I also don't like that the larger skillet has very low sides.  I think the picture was deceiving, at least to my eyes, so do a closeup on that if that feature is important to you.  I do like that they supplied several lids and that the pots and skillets are very lightweight.  Time will tell how they hold up.
