It is all I have used for the past few years (and white Pierco in the supers). No problems with having the bees use it.
Just had a thread on the fact that I have a lot of burr/bridge comb connecting frames between boxes. It was pointed out that the top bars are different (thinner) on plastic frames in general and they violate the bee space, so the bees build comb in between. It was also pointed out that Bee Culture published a table some years back showing which frames worked better with the boxes from different manufacturers (I don't have the table, unfortunately). Tomorrow, I am going to measure the space between some boxes and see if that is, indeed, the problem.
Otherwise, I love the stuff.
