While it is a big improvement over low power jewelry cleaning units, it doesn't have industrial grade power. Seeing that low end industrial grade ultrasonic cleaners start at about four times the price, I am satisfied with my purchase. I may have to run several cycles and use more than a drop of dish soap remove to stubborn gook, but it is a fair trade off. Note: be careful using the heater on some plastics. I had a friend melt the plastic handles on his Swiss army knife. I haven't had the same experience - so just take it as a word of caution.
