My Sentinel Prime arrived yesterday morning. I was originally somewhat disappointed (not least of which with the fact that mine came without instructions! I was a bit worried when I opened the box that I might have have been 'missing' missiles or accessories that would have come in the instructions-bag, but I don't think I did so it's not that big a loss.) I transformed mine to vehicle mode for the second time today and my second impressions are much better. Now that I've got the feel of it, it's a good solid toy, and as long as the parts are aligned, they click into place creating a nice brick of a fire engine toy (even better with the shield and sword locked away.) The shield is great fun too - I've spent many a minute clicking that thing back and forth from shield to scissors and back again. In robot mode the feet are clever and the guy is memorable and imposing enough to be a new Transfomers icon. (And hopefully, like all good Sentinel Primes, he'll be a jerk.)

My one question to people whose toys actually came with instructions and didn't throw out their boxart is - what are the grey rear-nozzle-hose/high heels/soft-serve-dispenser parts designed for? They don't seem to do anything in either mode.
