Perfect! It has arrived in good condition, taking, three weeks delivery in Barcelona. Curious little gadget, it works perfectly. It comes with a replacement glass and LED. Use pharmacy alcohol as fuel to avoid staining the glass with the flame. Five star seller and fully recommended. Thank you!!
It works very well and is very nice. easy to put into operation and very didactic.
Everything is broken, delivery is disgusting, flask is broken, board is broken, thrusts bent, even the metal body is broken, the engine cannot be repaired. Very upset
The product fully corresponds to the description, checked, everything works perfectly, delivery on time. I recommend the product and the store. Thank you
Nice and smart simple Stirling machine. For more fun you move an electric generator connected with a color changing LED. It came perfectly packaged without any damaged part . Very happy with this puchase
Runs great! Generates 3v which powers the included LED very well.LED changes many colors in different patterns.Love it and would recommend it.Comes with extra glass globe and extra LED and filler straw.Runs best on alcohol.I tried a tea light candle but didn't run as fast.
absolutely perfect
all ok
Product arrived on time and in good working condition . it was wrapped in bubblewrap foil . Add alcohol in the reservoir , light it up and let the heat to do the magic , After about 30 to 40 seconds it starts moving. Even if you shut the flame off it stils works for a few seconds as long as there is pressure left . The LED lights up in 4 different colors, Nice little gadget. Worth all the money. Thank you Banggod!! Recomended.
this is soooo great to show my grand kids
