Retailer reviews
Summarized retailer review data when available.
Very good and good instructions
Fun
Very well packed, but came directly from a German outlet in Flensburg, which apparently can do this. I have not purchased from Swedish amazon.se before, only from German amazon.de. It has always been poorly/badly packed, last time two books were simply thrown around in the box without any padding, and became damaged. The package arrived on time. Do they also do this from German amazon.de? I haven't built the concrete mixer yet, so I can't comment on it.
The set is good overall because of it's part usage including the gearbox but this set did not complete some parts like not filling in the gap on the roof of the truck and having no sideview mirrors but other than that it's a bit pricey but a lot of fun and has a lot of good parts. Good parts provider but a bit pricey.
It was a delicate task, but the finished product is very solid and excellent.
Exactly what my husband wanted, and it was very nice that I could receive it right on his birthday.
when assembling, I realize that the mill doesn't turn, the black gear is stuck. regards, adhoncoop
The mill turns on and off like a real one. Unbelievable how they manage to do that. Our 12-year-old grandson, who is a big fan of LEGO, was very enthusiastic. For my next purchase, I will definitely go back for the Technic theme.
It's a fun project to build.
Great article. LEGO sets are becoming increasingly realistic.
Durable and lots of fun.
It's very fun and educational to build the concrete mixer.
