Love them.
They seem dyed. But it was so much fun to build! They will work really well for frags. Be warned if you're messy with glue like I am you fingers will be purple when you finish. Make sure to rinse them really well.

Not great
It’s okay enough. Painted, seems overpriced.

Good size
Perfect for any wall building in a small tank

Versatile, but not very porous.
Good price. Easy to glue together to create original shapes. And also much more attractive to mount coral frags, rather than those ugly and inconvenient plugs. Not very porous material -- it's a hard, heavy solid rock.

Frag Rock
Frag Rock arrived, colouring comes of very easily so will have to see what that is like (perhaps normal for this type of product) when used, I've not added to tank yet, I'll be checking my water closely once added and will update the results.
