Bought multiple sets. They're built well and look fantastic, particularly the black set & the yellow set. The instructions are also well-made, and each step itemizes which pieces are involved.The trick with the instructions is this: read ahead. Always read ahead. If you're like me, you prefer to build duplicate parts like arms or legs in parallel instead of series, so read ahead, figure out which items will need to be built twice, and proceed accordingly.Would absolutely buy again.And will buy again. Seriously, these are the coolest sets in my collection.Wanted the Black Mech as pictured. The description explained a White Mech. Luckily it was the Black Mech.As for the product itself, the supposed "Easy to follow" instructions were not easy to follow. It doesn't tell you when you need to make two builds till the end and sometimes they don't clearly show where specific pieces go. While the overall build looks great, it is not something made for play as the limbs are easily removable. So if you are buying this for a kid, be warned that limbs may fall off when complete.This is honestly the coolest thing I've purchased. If I had gotten this growing up it would have been sooo cool. This is what I imagined growing up all my robots would look like. Will definitely purchase the others.I thought I was receiving the Dark Hammer like in the description of the details but it is not the same as the description. I was hoping that the Picture was a mixup and the seller would have noticed the picture is not the same as the description....I was wrong but I am going to keep it and collect all the rest.My nefew loved itBought 2 of them one did not have a part. Disappointed in it. Did not return it. Did not have the time. It said 3 plus u got to be kidding.it was missing a piece possible more, as i gave up building it once i noticed. The instructions are not horrible, but they are far from perfect, multiple bags and you need to open all of them to get started instead of open as you go. The company should look at how Lego has their instructions written and follow a similar style.
