Amazing set

Some of the best ninjago mechs so far. The build is very satisfying. And they look great on shelves. I would have loved to get full figures for jin and mira instead of only their heads

Incredible

This set is absolutely awesome, I love these mechs and most others from ninjago. I only had one issue there was a missing piece, a light gray bar tile, I had to change it to a regular tile piece. Other than the missing piece this is a lovely set that I would definitely recommend.
