I'll be straightforward. It looks great and has great range of movement but it's loose and some of the panels don't tap in right luckily the combiner ports hold good unfortunately for me in Menasor it falls backwards under its own weight at the knees. Take this its the knowledge that this is there first toy and if they release it might get better but the price has dropped since release.

Just got mine today. Hes very big. almost the same height as combiner wars Leader Megatron so good sized. The truck mode is a little small but that's easy to over look. articulation is spectacular. Very strong durable plastic and well designed. Now he does have issues. First when I got him out of the box I noticed when transforming him into robot that his right thigh was assembled backward. was scared I was going to snap it off so I took the thigh apart and noticed that the swivel joint just needed to be flipped around. may not be on every figure but it is something to look out for. second problem is his combine mode. he is extremely heavy! too heavy for the Hasbro stunticons in leg mode. so you do need to get the Perfect effect foot upgrades to make him balance out and stable. the truck cab(feet) are a floppy mess in combine mode but they do slide right off on some weird joint so you can just remove them for menasor and he looks way better. But with those minor issues aside I do recommend you get him. hes perfectly G1 accurate(even has his little roller) great size, excellent quality for this companies first figure, fun transformation and is 1000 times better than hasbros crappy optimus redeco.
