I haven't used a lot of the Pierco's but I have a few, just to see what I thought. I like them. I don't know if your's is Pierco or not, it's the only one I've had. But I have a lot of RiteCell foundation.
I like plastic. You don't have to wire it. It doesn't sag. The moths don't eat the foundation (but they will eat the comb off of it). Once the bees have drawn it once, it works as well as wax. But it's true, the bees seem to hesitate with it when it's brand new unless there's a big flow on. Wax coating (most is offered this way) and spraying with syrup, especially syrup with smell like Honey Bee Healthy or Wintergree oil, seems to help get them to accept it better.
But I admit, if I wanted plastic, I really like the PermaComb. It's already finished.
But now that I'm doing natural cell size, I don't have much use for any of it. The unregressed bees hate the 4.9mm plastic. I may buy more of it now that they are regressed, but they sure want a lot for it.
