Here's my TrDr review of the first 3 pack:
Cheetor: I don't see the point of that new mold. There's not much differences between this one and the Kingdom mold. Furthermore, the Kingdom mold is way better for the overall execution. Mainline Cheetor feels like a pale imitation to the Kingdom one. Plus, the beast mode looks like he's wearing trousers like some cartoon character. Still, on its own he's not that bad. And if for some reason you're late in the game for a BW display and have missed out on Kingdom Cheetor, he's a great stand-in.
Nightbird: She look great in both both mode and car mode, plus her transformation is interesting. Especially how the legs work. But mine have a feet wheel that pop off too easily (I'l lucky it was never lost in transit) and her weapon storage in vehicle mode is silly. Still, she's a neat little package and her tiny, tiny vehicle mode is cute and would go well with the Studio Series 2007 Movie Jazz.
Wheeljack: As expected, the controversial Wheeljack steal the show here. He's so great that the purchase of the whole 3 pack is worth it for him alone. The bot is awesome, no obvious hollows, the transformation is simple yet very satisfying, and the vehicle mode is just perfect. My only nitpick is that his vehicle mode is way too small. He would benefit greatly by being a voyager. Also, there's lots of real estate under the vehicle, so a place for the gun to peg under/inside the vehicle could have been done easily yet they didn't do it.
TlDr; This pack is simply Deluxe Wheeljack that come with bonus accessories.
And it's worth it, even at full price.
know of a better substitute for 100
