Hello:
I have been using the model 95663 for awhile and I like it.
I have used dishwashing detergent mixed with water cleaning all types of "stuff." It has worked to perfection. It has removed all types of dirt and gunge from engine parts jewerly,etc. I have not tried a petro based solvent in it yet as I have not found a need to do so. It works a well as an expensive model that I burned out by being ignorant about the used of an US cleaner. Mine also has a heater on it to warm the solvent. This model sells for $90.00.
One thing that I did learn in the past, is to permit the unit to cool after a use. They do not have an one hundred percent duty cycle. Perhaps a 50/50 duty cycle. I destroyed my expensive cleaner by not permitting it to cool between cycles. The model that I have has settings for 60, 120, 240 and 480 seconds. I have only used the 480 second setting. It really cleans jewerly at that setting! Engine parts came out very clean! I even used it to clean the parts for small engine carbs and they too were very clean! They looked like new.
For the price. I would take a chance unless one could find a better unit at the same price. I shopped for a cleaner and I could not find anything of the sixe of this one for about the same money.
Stay well,
Frank
