Customer Reviews
Easy and fun build
Got the low temperature difference Stirling engine. It was super fun putting it together, even for a first-timer. It actually works! It's pretty cool to watch. My only small issue was one instruction diagram was a little fuzzy, but I figured it out. I'm already looking at another kit.
Good kit, slow shipping
I ordered a DIY Stirling engine kit. The parts were high quality and the instructions were clear enough for assembly. Shipping took about 8 days, which felt a bit long. Overall, a solid product, but patience is needed for delivery.
Plans worked, quick download
I just downloaded some free power blueprints and an off-grid energy guide. The download was instant, and the quality of the documents was excellent. Everything was clear, well-organized, and exactly what I needed to start my project. It's great to have such detailed information readily available. I'm really happy with this purchase.
