I bought both these two packs too since the guys I wanted came in different packs
Air Raid looked cool on the back of the pack (and didn't disappoint either) whilst Storm Surge looked/is kinda lame (what's up with his arms/hands or lack thereof?)
I thought Clocker looked pretty ordinary (and still does) whist Hardtop was the one I really wanted in this pack... the pic on the packaging made him look awesome (which he is)!
Yeah you're not alone in your complaint about the clip things on the back of his legs... mine actually fell off a couple of times whilst transforming him, so I guess yours isn't an isolated incident - just a poor design and/or manufacturing process.
I feel kinda cheated spending $60 for both packs... the quality's just not really there - maybe worth $20/pack not $30
