Received the two smallest sets via Amazon and built them this afternoon.
Trailbreaker
Sure he is Trailcutter on the packaging and instructions, but I will continue to call him by his original name.
Fantastic figure made of all the same bits and pieces as the other blind pack wave Kreons, in that he is designed to semi-convert with the swapping of some additional pieces. He has 3 stickers to add to his larger brick count (than the blind packed waves) which are all used for his alt mode, which is okay, not great.
Robot mode has some one-off made pieces to represent his shoulder cannons. Putting this set together after just opening the Commander Trailbreaker, it is obvious that this is a G1 Trailbreaker with a small Bh enemy.
Trailbreakers Set
It's a poorly designed little green dragon, with three stickers and nothing spectacular or truly clever. A waste of bricks and time to construct. The Beast has the celverly made projectile firer in his tail, but due to the poor build design it is nigh unusable, rendering the only positive into another negative.
If it hadn't only cost me about $6 (shipping was more or less free due to coming in a large order) I'd be upset, but it is only $1 more than a blind packed Kreon bought off the shelf here.
If you can get Trailbreaker by himself cheaper than the whole set, do it. The rest is a waste.
Windcharger
Like Trailbreaker, this is another higher piece count Kreon than the blind packed figures. Another three stickers all for alt mode and lots of leftover bricks in robot mode that can only be used in alt mode. Figure itself is nice.
Windchargers set
Do you have 3 minutes? Then you can make this set, disassemble and remake again. The Beast is 9 sockets joined together. The weapon firing mechanism is not only cleverly designed, but it works surprisingly well. The enemy is useless and not at all clever or fun, but the luncher is different and clever. The first time a Kreon build has ever felt like it was designed by someone with any idea of how to capture the "lego" feel in a non-lego set.
Overall Windcharger is easily worth the $6 or so it cost me. I'd happily pay a little more (on par with the smallest lego sets) but nothing over $9-$10.
