Purchase of the year - very satisfied :) On 26 Dec 2023 I ordered Stirling Engine Model with Electricity Generator and Bluetooth Singing Tesla Coil in beautiful blue color. After 12 days, I recieve good protected package, with no damage, delivered direct to Switzerland. Perfect toy, no only for kids but also for engineers, like me :) , works perfect as described. Highly reccomended, I will definitely come back. Thanks :)

Successful Christmas because of enginediy! My mom really wanted to find something for my son to build. He told her he’s interested in doing something with his hands for a career vs “going to college”. My husband is a mechanical engineer and their brains work pretty similarly. I was so happy to stumble upon enginediy.com. We decided on a small one as he is only 12. He built it pretty quickly and LOVED getting it to run successfully! It’s a combustion engine and we already need to go buy more wick for it! I’m glad he will have something to set on his desk for a very long time.

Total satisfaction. Have been in contact with the guys at enginediy regarding a shipment from them. The model engine was not only sent quickly and received within a few days, but the quality of the kit was outstanding. I didn't know what to expect with this sort of kit, but I really am not disappointed. My communication with them afterwards has always resulted in swift and very friendly replies. I would have no hesitation in dealing with them again. I definitely recommend them.

Steam Beam engine. I was pleasantly surprised by the finish of all the parts. More so by tiny ball bearings. Need to read double check instructions. Classic RTFI. Else go back undo, do again according to picture. Very free running with careful assembly. As much a display piece as working model. Note flywheel already has grub screw installed. Model even turned over on blowing into boiler. This the beam engine. Very happy. Only just enough screws:-)

Retrol HM-01 Hit & Miss engine. In 2023 I pre-ordered a Retrol HM-01 hit and miss engine from Enginediy which I knew would take a couple of months for delivery because it was still in pre production. I was happy to wait and I was kept informed of progress and expected delivery. It duly arrived very well packed and beautifully made. This was my first attempt at building an engine but it went together perfectly. The instructions were mainly pictorial and a little more written description would have helped but all my questions were promptly answered by their excellent service department. I have been running this engine for four months now and I’m delighted with the design and quality. I would certainly recommend Enginediy and will be using them again.
