Brickset
“Kai’s Mech Jet is perfect for what it is, a 2 in 1 vehicle with bright coloring. The minifigures are fine, but not a reason to buy the set and there are very few rare parts. The half dozen stickers will likely deter some, but that is to be expected for a £19.99 or $19.99... More set. However, for someone looking for a smaller sprightly set, Kai’s Mech Jet is certainly a sensible choice.”
