Have to say I was really sceptical about Springer, but this is one solid figure, maybe even the best of the current Generations line. Bot mode is well proportioned, has a ton of useful articulation and ROM, and very little kibble. His gun has a pivot in it so you can angle it in car mode. His sword has a fairly complex transformation that locks the handle (which spins) and looks functional in both forms.
Car mode is cool with all of the obvious helicopter parts hidden inside (including the sword which tucks underneath. Only real downside is the windows don't like to snap in completely, but the slight gap isn't completely distracting. Helicopter mode isn't as good, could really use a more obvious tail rotor, but it's not terrible, passes well for cybertronian. His feet are kinda loose so they flop around a bit in the back. Snapping the gun to the front is a little tricky, but looks better than the default front landing gear that folds up inside.
All in all it's an extremely satisfying figure for the price. Too bad I've heard Blitzwing is pretty shoddy, but I'll be getting Sandstorm for sure.
