    This is a great set to assemble, but it is ridiculous to have it shipped in its original box. The original LEGO box is not designed to be slung around by the shipping companies. I could not believe that the seller would not put it inside a cardboard box to give it some protection. I'm not a collector, but I imagine someone who liked to collect the sets would not appreciate all the shipping labels stuck to the box.

    Please be aware this won't come in a brown Amazon box, so if you buy it as a gift for your husband like I did, they will find out what they got for Christmas the middle of November. Why? Everything I order from Amazon comes in a brown Amazon box. Why not this? So disappointed. (the kit itself looks awesome though, I'm sure he'll love it. Just wanted to send a warning to others).

    This isn’t about the build. I’m sure that will turn out great.

    Some people like to keep the box. It wouldn’t have been hard to find a box to fit the Lego box so there’s less damage to the box. Try a little harder.

    Great set. It was supposed to be a gift though, so it wasn’t ideal that Amazon put the shipping label on the Lego box & shipped it that way. Spoiled the birthday surprise when they saw the giant Lego box on the porch.

    Good display piece
    This set is a good display piece but not really a useable set to combine into a larger display.

    The box was missing lots of pieces and a few bags!! For the price you would think Lego would double check before they box and ship. Thank you to Amazon for sending me out another set that I could use that one to complete the tree. After all that the tree house is a fantastic build.

    Fun set, but it's not color-blind friendly. There are lots of pieces that are otherwise identical but differ only by color, and are dark red / dark brown / dark green, which color-blind people will have a very hard time distinguishing. This is true for both the pieces themselves and for the images of those pieces in the assembly instructions.

    There was nothing wrong with the LEGO set itself, but it would be nice if it was shipped inside a box and not shipped as-is with a shipping label on the box. I save my boxes and shipping them as-is with a label damages the boxes.

    Il faut mettre les sacs du bulles pour protéger la boite Lego parce qu'il y a de le petit dommage "léger" et je veux avoir la boite soit "parfaite" pour la collection. Pour la prochaine fois, s'il vous plaît de mettre toujours les sacs de bulles pour éviter de endommager la boite de Lego pour la collection. Merci.

    I was not a Lego fan when I grow up. But this year I got this Lego Tree House for my girlfriend as a Christmas gift and she loves it very much. This is also her first Lego kit. There are 3036 pieces in total which might be somewhat overwhelming but the manual is easy to follow. It took us some time to finish it. I love the fact that it comes with two colored leaves, one in green and the other in yellow. The price is somewhat expensive compared to other branded. My suggestion will be finding a plastic cover for it since it will get dusty over time.
