"I bought this set for my wife who photographs LEGO sets and MOCs as a hobby.
That being set, this set is perfect for her as there are many customizable options that are available! The price is a bit on the higher side for me as I would've expected this to be priced the same as Drifting Diner.
The build is quiet easy and I was able to build it in less then an hour. There are a moderate amount of stickers which is great! (My fat fingers make it really difficult to deal with small stickers and/or a large number of stickers). The karts are quite colorful and make for great pictures!
Combining this set with the Xtra Road Playmat (Set ID 853840) or the Heartlake City Playmat (added below) could probably better the playtime of this set. It is very easy to lose the tool kit in this set and is not available as a replacement in LEGO Bricks either!
A MAJOR flaw in design that I noticed is that the handle of the kart is too far out for the mini-doll to reach! I was very surprised to see that and when I looked at the instruction book, I noticed none of them are actually holding the handle!!! This must be addressed LEGO!! That's my only negative remark about this set!
Will post images after I find a fix for the handle!"
