Well, being a staunch collector of all things Soundwave, I had to get this one. My expectations were not high, based on early photos and recent reviews and the best I can say is that Sonicron lives up to those low expectations. I transformed him once, but given the feel of the plastic and the tightness of some of the tabs, I don't think I'll risk breaking him by doing it a second time. The payoff isn't worth it anyway.
Despite the odd proportions, I do still like him as a display piece. Also, the leg joints on mine are much tighter than the ones in the videos, so getting him to stand has not been an issue. It might be because I've transformed him so little or perhaps the screws are a bit tighter on mine; maybe I just got lucky.
All in all, it's sad considering how nice the toy could have been, but he's unmistakably Soundwave, so he gets a spot on my shelf. Hopefully someone will take the same base design and do it right in the future.
