In case anyone is thinking of getting him. Although $300 is a lot of money in my eyes, that's £229.06. As comments have said they are pretty much just display pieces, but there are other reports on qulaity issues with other masterpiece figures? How true this is I don't know. Does anyone else own any MP figures? Do they last and have you had anby quality control issues with the figure out of the box?
I watched a review of MP BW Megatron last night and the reviewer brought up this issue. Showed how to do it properly and also said that it's only really the first time it's an issue. Another issue with the figure is just getting all the panels lined up properly for beast mode.
I've got the original MP Skywarp and Bumblebee. I don't have Skywarp on display any more because the stand cracked (the figure got bumped, not from degrading over time or anything). Skywarp was definitely more of a display piece. The transformation was pretty complex and took a bit of time. Bumblebee, however, is the opposite. He's got a nice transformation, doesn't take up much shelf space and is just fun to transform back and forth a couple of times when you need something to do with your hands.
I think in some parts (Having watched a couple of reviews now) there are parts that have thinner plastic, but I can't see how it would crack at the pelvis when it slots in easily enough, unless they're being heavy handed. (Apparently it's swirly plastic, perhaps a couple were miss-assembled when the legs were attached to the pelvis in production given it's a weaker plastic) I know the first release of G1 MP Megatron was notorious for breaking allegedly. As long as it's taken nice and slow - the transformation and not rushed it might not be an issue.
That said, it is a really nice figure with the jaw and tongue for that "roar" and the rolling eyes, really nice figure.
