No customer service & they delete negative reviews I've made several orders from them and always got what I ordered. One expensive item (<$1K) arrived with some inexpensive parts missing. I provided them with the prod #, missing parts#, part description, & photos from their assembly manual. Many emails were exchanged. Still, the service tech was unable to correctly identify the part. He guessed at it and twice sent me the wrong parts and then gave up. When I wrote a negative review, they pulled it off their site.

my trusted agent the knowing that the investment in the item being shipped is in the best hands and care ,as if in your own hands.

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 :)

Great and Respectful Service I like EngineDIY because they always do what they say they will do. If you have any problems assembling one of their excellent kits, an email to enginediy.com will get you a quick reply. I recently purchased a very new model. Understandably, there have been a couple of production bugs, causing me to email EngineDIY to ask for replacement parts. They were sent to me without complaint as soon as they could source them. You are safe with EngineDIY. Recommended!

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.
