Very nice and awsome

My son loved this gift! He is 12 and put it together easily and had it working in a few hours! It is a really fun project for any kid who loves things like STEM or Lego building!

Great project, wish it had more instructions. Lots of fun to build.

Took about a week to put together, just doing a little bit after work every day. Overall was a fun kit and it was neat seeing it work after it was complete. I only have two gripes. The first one is that instructions are pretty vague. The bags are numbered, but the numbers have absolutely nothing to do with the instructions. Also, once it’s all put together, it can only run for a little bit before the driveshaft comes undone, but that’s a minor thing since it’s just building blocks. I saw other reviews saying that they had missing pieces. Mine didn’t have any missing pieces. In fact I had a few extra. Maybe I missed a step? As far as durability, it’s not the most durable kit, but it’s not bad either. It’s what you would expect from a miniature engine built out of offbrand Legos. So overall, given the price, it was a good kit and I had fun with it, and I would recommend to anyone curious about it.

My fiancé loved building this!

It very fun to build. First type of this model I have done. Looks great and engine does turnover with battery motor provided. Looking forward to my next one, it is sports car. Nice assembly instruction book. Very sturdy, parts snap together with procession cuts. Multiple layers to assemble so interesting to build. Pistons and crankshaft turn with ease with battery motor provided.

I absolutely LOVED building this and all the parts move as depicted. I display it on my coffee table and everyone thats seen it has turned it on and asked where to get one! I love Amazon! Ill be buying more of these!

This build will frustrate you to no end. The instructions are terrible, whole steps missing, the pictures are unreadable, and the pieces are broken or missing. Just spring for Lego.

Muy entretenido, si lo disfrutas puede llegar a ser relajante, muy intuitivo y funcional

Muy didactico

Funcional

Me llegó incompleto y es frustrante! Apenas inicié armándolo y resulta que me falta unas piezas ya revisé en cada una de las bolsas y no viene Qué lástima…
