I finally opened mine this week (I can be a procrastinator) and I like it.
I bought it mainly for the convertible car mode. As far as I know it's the only one of its type. Yes he has no floor but you can't really see it unless you're looking straight down on it
I would have preferred it to have a more shinier paint app but to be honest I don't mind the grey.
I'm not a big fan of the grey tabs that poke out the back of the car. But I do like he has a steering wheel, which I discovered while playing with it in robot mode ("what's this thing sticking out? ooooooo a steering wheel!")
Unlike ROTF Sideswipe/Swerve this is hella easy to transform. I was even able to do it without the instructions while watching TV last night, which for me with a movie toy is an accomplishment. I had no trouble with making panels click together.
The mechtech weapon is a bit superfluous - even my kids asked why a car would need a sword - but it doesn't hurt to have it.
One gripe is that the screw holding his head together doesn't seem to attach properly. First time I transformed him his head broke into two. Unlike my experience with Swerve I was able to put his head back on.
