I've never used a lid on one and one still broke.I don't usually put a lid on, maybe that helps?
from what I have seen, I don't think there is a type that doesn't workAny cheap ultrasonic cleaners online to buy that work decent??
They're slightly less effective because of their lower density; therefore the energy waves aren't transferred through quite as strong so the cleaning capacity is a little reduced. This is in my experience, and have discussed with others in this regard too. Also, the plastic containers often need to be weighed down if the contents are <1 SG.Great thread. I have always wanted one of these, seems like a great item to tell family about during the holidays.
EDIT: Seems like plastic jars/containers would work great since some glass jars brake in these..
