Retailer reviews
Summarized retailer review data when available.
Nice LEGO box, fun to build and play with, may be a bit fragile. Dad builds, kids play.
amazing, takes a lot of time and precision, a real challenge. but if everything works out in the end, you can be proud of your bears. no downsides.
A lot of fun!
Very good work, really. The instructions are perfect. It took about 50 hours to assemble.
It is a great product.
I bought this a few days ago and I'm very happy with it. I've been working on it for a few hours now and I'm still not bored. Everything is also packaged by number and step, which is very convenient. I don't have to pick up the whole table this time, my partner also finds it fun :)
