Review: Really well detailed build and a great investment for a hobby - About the experience its a massive set - so it will take time , but it is a really pleasent experience, hats off to the designers to make the whole process a seamless routine. Great details overall, the special parts for this assembly seemed to be really nicely made, nothing too small. 4000+ pieces is a challenge in itself - but everything is arranged and sorted neatly to follow the steps for the build. Once built and setup the movements are really precise- precise in terms of a LEGO set. And the assembly does seem to be really sturdy Moement of the caterpillar tracksis limited to few surfaces , but it works well on flat areas. its a great build for hobbiest's, or for young adults, I wouldnt recomment kids to work on it by themeselves as it requires quite a bit of patience. Drawback the app is a bit irritating at first to use, it doesnt seem refined to work on a touch screen device. The whole machine does require 12AA batteries- I really wish LEGO would just provide a rechargeable setup for this build. Shipping i got this shipped to India through desertcart.com- really fast convenient from the seller to ship it . but yes there will be a lot of delay at customs and usually they will open up the box to check the contents for "security purposes"- it is a risk but not much of a choice on that front.

Awesome set and great way to get motors and specialty parts

### ⭐⭐⭐⭐⭐ A challenge but well worth it.
*by T***R on June 23, 2020*

My third Technic and what fun they are to build! The engineers who design these Technic toys are incredibly smart. Instructions are well written but you must pay careful attention to every detail when building as missing one note may cause you to disassemble in order to correct the mistake. Luckily all the parts simply snap together so disassembling is not a big deal. The motors (5) and controllers (2) are all state of the art and work intuitively & flawlessly from an app on your phone.
