I think it varies.
For me, I've managed to avoid the spoiler scratching any point off but granted I've only given it one go. Part of my reservation is due to that very reason.
As I understand the list of gripes are:
- Spoiler scratching when going to truck mode Big? I think so if it is a widespread problem. I haven't personally experienced it yet but I took great care. Some others have not. I slide it in gently and slowly and then out just as gently and slowly. Personally it's not a problem for me but if I experienced it, it would make me pretty furious.
- Guns not holding hands Big Depends on how much you care for weapons. I care a lot about them but they still fit. It's more a chore but definitely not a deal breaker. I also love the saw too so often don't use the gun.
- Wrists giving way too easily when holding the big gun in Rodimus Prime mode. Big? I think so if you like playability a lot. You can get it to pose but it's a pain - even more so when you are changing poses regularly.
- Stability for posing Big? I don't think so. For msot people who display it should be fine.
- Limited diecast. Big? I don't think so. Figure is very good in what it represents and that should be what matters.
The transformation, I repeat, the transformation is not QC ridden. It's a challenge but if you follow the right process (which I believe I've gotten the hang of now), you get a very nice, gap free Hot Rod.
