I bought this so my kids (8 and 10) would have a basic understand of how an engine works and what the various parts we called. We spent about 2.5 hours building it and talking about what everything is and what it does. When we finally got the part where the timing belt get installed, it snapped instantly! "No problem" I thought, the model comes with a second one and we'll just use that and be a tad more careful this time. That worked, we finished up the model and let 'er rip! Everything worked great. The next morning, we went to plug the battery pack back in and the timing belt had broken overnight! On top of that, one of the connectors for the battery pack pulled out of the case when unplugged it. the Emailed the vendor, told them what happened and we had a complete replacement on our doorstep in no time at all. Honestly, it's a bummer when something new like that break instantly. Especially when you put bunch of work into it and more so when there are kids involved. However, the vendor responded to this situation VERY well and made things right immediately and that's a hard thing to find these days. On top of that, I got to teach the kids ANOTHER lesson out of this; you can get mad and leave horrid reviews of a product everytime something bad happens or something breaks, but in the end, you're probably still going to have a broken product.....or you can explain what happened and be a decent human about it and you stand a much better chance of getting what you need. .....and by the way, the new timing belt we received is still hanging in there!!!!!!

My son is obsessed with motors, fans, things that move, etc. so I bought this kit for him to put together and play with. We've had this kit for almost a year and he still plays will this (takes pieces off and puts them back on, tries the pieces in different spots to see what will happen, pretends to fix it like he's seen my dad do, etc.). He was 4 y/o when I bought this and he did need hand over hand help putting it together the first time. With practice, he's capable of taking off most pieces and putting them back on himself. As long as your child knows how to use a screwdriver, can handle small pieces, and knows how to read instructions, they will be able to put this together without help. Once its assembled, I would say its appropriate for kids 3 y/o and older so long as they know NOT to put small items in their mouths. Read more
