Customer Reviews
Always a good experience
Got another V8 engine model kit. Like always, assembly was engaging, and the parts were all there. Delivery took 8 days to get to me this time, a little longer than my last order, but still within reason. Enginediy is consistent.
Good kit, slow shipping
I ordered a Stirling engine for my dad. The model itself was high quality and he's enjoying putting it together. Everything was packaged well. However, shipping took almost two weeks which felt a bit long. Their customer service did answer my tracking question quickly though, so that was good. Value-wise, it's pretty good for the price.

hey, anyone ordered a kit from Enginediy to, like, California before? curious how long shipping usually takes. trying to get one for my dad's birthday next month.
are these kits actually good quality? seen some similar stuff on Amazon that was kinda flimsy. wondering if Enginediy is legit or just another drop shipper.
