Hard (impossible) to start

If you buy any ultrasonic cleaner do not put your parts to be cleaned or the 
cleaning solvent directly in the tub.  If you want to keep the machine 
clean, only put water in the tub then place a cleaning vessel into the tub 
with the cleaning solvent and the parts to be cleaned.
You need the water in the outer tub to transfer the vibration to the liquid 
in the inner tub.  Glass, hard plastic (nalgene) or metal inner tubs work 
best at transferring the vibration.
If you do use volatile solvents (acetone, gasoline, kerosene etc) they will 
evaporate quicker with the vibration so use them in a well ventilated area.
