The positives about this figure is that it's the only PCC commander figure I know of that is able to hide its combiner joints in vehicle mode. The commander vehicle mode for Double-Clutch looks awesome too, who knew that silver flames looked good on a bright blue car?
As for the drones both my leg car-drones don't automorph completely when I connect them to Double-Clutch, I have to open up the red car's bonnet and pull back the top of the black car.
The negatives about Double-Clutch is the combiner mode, specifically at the combiner-arm joints. They're both on these panels which are meant to peg into the car body but there are these other panels there that get in the way, making the pegging difficult and thus transformation into a combiner figure more inconvenient than need be.
Overall the appearance of this figure is very pleasing and the transformation is somewhat simple too, save for the difficulty with the leg drones and the combiner arm joint setup.
Of the 5-Pack PCC figures, Double Clutch is my favorite because of his least-combiner-kibbled vehicle mode. If you don't have any 5 pack PCCs yet, then this one is my first recommendation followed by Mudslinger, Skyburst and then Bombshock.
