My daughter received one of the add on packs for C-mas (from us) thinking it went with the regular monster high dolls. When she found out she couldn't use it...she went crazy looking for them. We read all of the reviews on other sites (most negative) so we weren't expecting much, but just in case, when we did find them, she used her money to purchase all of the sets. We were shocked, when we got them out, but in a good way. The dolls were well constructed and sturdy. I didn't expect that when you have to pull the pieces apart each time. The color differences really bothered me at first, but you would be amazed at how cute the dolls are that we came up with. Even other people comment on how cute they are. Now, the bad part. The hair actually wound up working pretty good to start with. The wigs are made like the LIV dolls (which I've read fit better than the MH wigs), so they have that annoying plastic peg. The longer you use them, the worse they fit. We've figured out to squeeze the head when you go to put it on, and it helps. Another thing is that the clothes are really cheaply made. The regular MH doll clothes are made well, and look good. These start coming apart after several good playing withs, and to be honest, there's just not much to them. As for the plastic pegs that hook the arms on, they worked well at first, but are starting to get weaker, and bend sometimes. I'm not sure how long they will wind up holding out. All in all, it's my daughters favorite toy. She's 12, and hasn't put them down in days. Even though I had my doubts, it's one purchase I don't regret.
