"First things first, this set looks amazing. It's definitely the best looking AT-AT version and one of my all time favorite Star Wars Lego sets in terms of design.
The build was fun, no boring or repetitive phases, a smooth process. I built it with my 7yo son who is pretty advanced for his age and he didn't have much trouble. It's also very big, but doesn't take up too much space which is cool.
Now the downside: this set is in my opinion very difficult to play with and needs extra care when moving it around. The legs are flimsy - if you leave them at an angle there is a good chance it will fall due to being off balance or the legs can even give in and it will slam on it's face. Some pieces/panels come off easily. It's especially challenging for a child but not entirely trouble free for older kids or adults if you want to move it around, open the hatches, move characters etc. As a display piece, it's fantastic and I would buy it again!"
"This is a substantial, fun to build set. The size is quite optimal for having the right shape and details while maintaining playability.
Obviously the tricky shape of the ship makes it challenging to design but this is the best version so far, if not counting the UC one.
The way it opens is a huge improvement to prior versions, with 5/6 lids that open. However, some of them are very flimsy due to the challenging shape. Especially the lid next to the cockpit, the hingle is simply poorly designed and placed.
There could be a little more details inside, the "kitchen" corner is quite empty and could use some more interesting elements than a frying pan and a coffee mug...
An annoying flaw are the top and bottom turrets which do not stay in place and break constantly. The four "barrels" on each are the most prone to falling off way too easily. If you open the round hatch on top, the cannon swings around and gets in the way. I know the size makes it a challege to implement these but this just doesn't work. Also, the top hatch with the vertically sliding "thing" - what is this supposed to be?
The characters are fun but I don't understand putting a one scene side character (Boolio) in a set. There are countless more relevant characters to put in there"
