I filled it with 2ml and let it run 20min continuously. After 20min run time I looked after and are still 1ml left. Runs without problem. Test video is in YT.

The product works. somebody complain with its noise, and indeed it's loud...changed the motor with another one i had, works slower and so much less louder. Somebody on youtube solved removing the motor and putting a fan. In my opinion, the system motor-piston its better: it simulate the flow of smoke exactly like a real motor, meanwhile a fan simply flow air countinuously. On the otherside, i would like to try to connect the motor to an esc, in order to have smoke increase the flow gradually with speed increasing.
