The Brothers Brick
“I'm pretty impressed with this set. Other than that sad excuse for a sword stand, there's nothing about this set that feels cheap. There are no obvious places that feel like LEGO cut pieces to lower their cost. Speaking of cost, at $70 for 968 pieces this set comes in at... More only 7.23 cents per part. And there are some really nice pieces in there, too. You get new minifigures, printed parts, hard to find colors, scarce elements, unique elements, and even some new printed parts. The build is fun and involved, the model looks great, and it has great play value. Yeah, this ticks all the boxes for me.”

“The 71720 Fire Stone Mech is one of the larger sets in Ninjago's 2020 ‘Master of the Mountain’ subtheme. He’s a big fella too, weighing in at 667g with a total of 968 pieces including 5 minifigures. Aside from being a good build and a fantastic looking robot Samurai warrior... More (what’s not to like?), you’re getting a lovely bundle of parts.”
