Honestly, I haven't put them together yet so I probably shouldn't be reviewing it, but I did kind of start it. It's nothing to actually do with this particular piece, it has to do with the metal puzzles to begin with. I didn't mind going out and buying needle nose pliers and wire cutters, but I don't feel confident in working the pieces to be perfect and so am worried about how it will turn out. The second piece I had to put on was the very top, which is supposed to be round. I've got it in the tabs, but pretty sure it's not going to look perfectly round when I work with it. There are a lot of really nice metal puzzles, but I guess they'd be more for people who actually know how to work with metal, so I guess I'll have to stick with the crystal ones.
