Product arrived expeditiously, simple packaging - nothing amiss. Construction above average. Works beautifully with the appropriate photon feed. Exceptional value. Highly recommended.

Really cool. But need more options to add can't find very many part's

The quality of the product looks great. My Grandson has not seen it yet. His birthday party is tomorrow. I will follow-up after he builds it.

I really enjoyed assembling this model kit. So much detail! All of the parts went together exactly as the instructions stated.
Since there was no oil included in the kit, I used some white lithium grease that I already had. Works great and should last longer than oil.
Since there is no glue or permanent fasteners, I can take this one apart and put it back together. It will be useful for teaching my grandchildren the basics of internal combustion.

I am very happy with the quality of the parts I got from EngineDIY for my Kacio boiler and steam engine.

It took a while to clear some other projects but I was able to complete the build in three evenings. Understand I'm 81, with one working arm and some hand tremors. Using some blocks and extra tools, the kit was relatively easy to assemble. The quality of the parts was excellent. Everything fit and adjusted very well. I'm looking forward to building a "hit and miss" engine next!

Just fine with the product. Great all around.

Loved this generator from the modent I saw it. Watch my full build of a base, simple electronics etc with MUSA HM01

Very nice tank its actually twice as big as i thaught it would be this tank is made very well

As a technology fan, this is a must-have - it's fun to build and marvel at.

The quality is very good

TOP support from the manufacturer - a part was missing and this was delivered within a few days - uncomplicated and very competent support

When I first saw the ads for this kit, I thought, very attractive model, but look at that price! Never the less, I ordered one and when it arrived I was completely reassured. On examining the kit I found that there were NO compromises, every component of the kit is premium quality. The design, fit and finish are superb. Assembly was straight forward and each step was clearly described and illustrated. I would recommend this kit to any 93 year old wanting to give his great grandkids some excitement.
Rest assured, the quality is so high that it will be treasured for generations.
