woefste Perisphere And Trylon Games Haynes Build Your Own Internal Combustion Engine

good for teenage

12 year old girl built this engine in 3 hours. Took concentration. But works brilliantly. Fantastic educational tool.

I read a TON of the reviews and decided to buy this one as a gift for my husband and my brother (ages 41 and 51). I bought extra stuff like screws and lubes and a file because several reviewers said the parts that it came with weren't top notch and needed a little tweaking to fit correctly. I wanted my husband and brother to enjoy the experience so I went to all that trouble (but didn't need to) and got extra screws and stuff. The reviews said this would take a several days to complete, but (ha ha) my husband and brother completed it in about 2.5 hours! My brother is a professional mechanic, so he has a huge aptitude for this kind of thing. I felt let down that the experience wasn't longer lasting for them, but they assured me they had a blast doing it. AND... I could tell they really enjoyed working on it together. They were laughing and having a great time figuring everything out. My sister-in-law and I just sat in the other room drinking wine and enjoying watching them have so much fun. It's like Lego's for adult men. So, in summary, I would definitely recommend this product "as is" and I don't think you need to go out and buy anything extra to make it work. Everything they needed was in our kit and we are very pleased. I just wish I could find a more complex model to "up" the challenge next time! Thanks so much for a great product and experience!

Good response from seller to queries and the product reached well on time considering it is an international shipment. The item was great, though there were issues with alignment and I had to do a bit of jugaad to get it done. It is nonetheless a very nice way if explaining engines. Assembly has to done by someone who knows a bit about engines. You just have to follow the instructions to the letter!

Good for children
