After having a TON of alignment/tolerance issues with Thundershred (got him today from BBTS), I decided to cancel my pre-orders for the other two not-Insecticons. The figure looks nice, but if I can't even transform it without parts being misaligned (couldn't tab one of the legs into the crotch, it just forced out every time, couldn't get the insect leg to stay tabbed into his body) then it's not worth the money to me.
On the bright side, I also got my City Commander today and it's wonderful, I combined it with my Ultra Magnus and have him displayed next to my DIA commander. It was a lovely surprise to find that CC came with extra face plates so I was able to swap the face on my DIA commander for one with the more Optimus Prime-like face shield

.
After my experience with Thundershred, I've definitely lost some confidence in FP, but maybe it was just 1 bad figure out of the lot. Hopefully others won't share my experiences.
By the way, for those wondering, since I saw it asked, I went ahead and popped his chest off. It's held on with two large tabs that fit under its chest. You have to remove the screws on the sides of the chest and separate the two halves of the figure to get it off, it does NOT open (no worries, I didn't dismantle it until after it broke, otherwise I would not have done so but figured why the heck not since you guys were wondering).
