I finally got to open mine up the other day and despite only recently getting Ironhide (and playing with it more than usual for a MP toy), I wasn't bored or felt like it was a chore to transform Ratchet, as this design is just a delight to transform. A little tricky with the chest area, but the result still amazes me every time I transform this mould.
And the legs... the way they turn into cartoon legs and hides everything... one of the best (since MP-01).
