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!

Just go ahead and pull the trigger! The ordering process was easy, tracking info was timely, and engine was packed carefully. I incorrectly thought a component was missing and contacted customer service. They quickly responded with directions to find the part in my kit. i am so happy with Engine DIY tgat I bought ANOTHER product from them!

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.

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.

Great product-excellent fit and finish - superb service I was pleasantly surprised by the excellent fit and finish on this mini drill press. Very well made product. Was looking for a small tool to do some very tiny work on the deck of the boats I make and yet take up little space on the workbench. And this does it well. Well worth the price and love EngineDIY free shipping and fairly fast delivery to Canada - hassle free for sure. Had an issue with the power supply not included but the Customer Service came through and solved my problems immediately - Good Job!
