This little unit is great. I've owned lots of import ultrasonics - they all have their pros and cons. The ones with drains are nice when it's time to empty - but the drains are plastic inside and can crack and leak. This one doesn't have a drain, but it's such small capacity it's not really an issue. I love the smaller units for job-specific cleaning, to prevent cross-contamination and wasted cleanser. This one is better than most this size, as they often have baskets that don't really fit.
