Playz Inline 6 Engine Model Kit - Build Your Own STEM Inline 6 Small Engine That Runs Kit for Adults & Kids Age 10-12+, Visible Inline 6 Mini Engine Kit That Works for Adult w/ 230 STEM Parts

My son and I had a blast putting this model together. Lots of detail and opportunities for conversation about how and why it works the way it does. I will also note that it has a fair number of delicate plastic pieces, care should be used when assembling. In fact, my son accidentally broke one piece - but Playz came through in a big way. Those kind folks were very supportive over email and sent a replacement part quickly.A+ product and an A+ company. Definitely recommend.

We had a broken blade in our Playz V8 Model Engine. When I contacted customer service by email Janne with Customer Care took care of us. When the replacement part was sent it arrived promptly and my Grandson who is 11 was able to finish his project. This was our first purchase though Playz, well made product, the description of engine is right on. This has been a great teaching tool for my Grandson- and his Papa enjoyed teaching him the functionality of the parts as they put together.

I thought this would be a great model to put together with my 10 and 15 yr old boys. And it was as far as the model aspect of it. All the pieces were there, and the quality of plastic was so so. The instructions were enough for the boys to do it all on their own. I just told them about the parts as they did the assembly. It took a couple of hours without my interference, and we had an absolute blast putting it together! When the big moment came to turn it on and let the boys bask in the glory of their work they were met with a clicking and grinding sound and nothing was moving. We took a look at everything and made sure everything was exactly the way it was supposed to be, and noticed the cheap plastic material they used for the belts wasn't allowing the belts to move.Now we are stuck with a model that doesn't do what it's supposed to because they cheaped out on the belt parts.Some advice I have to those that choose to buy this kit. Make sure you have a bottle of gel superglue. Some of our holes came stripped out and a little drop of the glue held the screws perfectly.Overall this kit gave me time with my boys that I really enjoyed. They loved putting the engine together, but were very let down when it didn't work. They really need to put better belts in the kits.There were little things like the stripped holes that could easily be fixed that didn't really add to, or take away from the value of the product, but it came with plenty of extra screws if they were needed.I may update this after I speak with customer service to let you all know how that experience is.***UPDATE*** 2/27/24Playz support team reached out to me after my review, so I was really impressed with the initiative they took on their end. They were extremely helpful and went out of their way to make the problem right.With the way their production is structured they couldn't just send me new or nicer timing belts so they replaced the product for me. Unfortunately this model had the same belt issues though the engine at least ran this time. I had a great time with my boys assembling the engine again, and just for the sake of exploration I plan on finding a replacement set of belts. Once I do I will post the link here.In summary, after the initial 3 star, I brought the rating up to a 4 star due to the excellent customer service. Its a fun project to work on with someone else or by yourself, but some of the parts run a good chance of being flawed. Taking everything into account the purchase was worth it to me!

An awesome gift for the budding engineer in your family! Our grandson had a great time putting it together and showing it off once it was done. It provides an amazingly detailed view of the functioning of an overhead valve V8 engine.

I bought this for my grandson to build and we built it in Christmas at 2023. I believe he absolutely loves it. It is still on his dresser today when you push the button it still works great a very good learning project for kids who like cars and trucks.

We liked the level of complexity and the modelling shortcuts were appropriate, but at the end, the timing belts do not work. They are too stiff (made of plastic rather than rubber) and aren't able to be realistically (or even simply) tensioned. As a result, the 4 hours of modelling was truly enjoyable, but the end product isn't able to show the correct timing of the spark plugs firing near TDC due to the plastic belts slipping and coming off the valve train and crankshaft gears. Please send rubber or rubberized timing belts !Addendum: THe Playz company responded by refunding my purchase AND allowing us to choose another engine model. WE chose the V8, have it in hand and will begin building it this month. Their customer service is unbelievably good. As a grandparent with "engineer-like" grand kids, I'll be back.
