A nice compact unit that seems to work okay. The major drawback in my book is the 3 minute timer that is about 2 minutes in duration. It would have been better served if it had a consumer controlled timing.

Works OK, not great. But in all fairness, it's a fairly low cost unit. If you want really great cleaning better spend more.

I purchased this product to clean my Invisilign retainers. It did an okay job for almost a year but then it died on me. This equipment might be a good idea for occasional use but not everyday. Reliability is not there yet!.

I bought this item from Jeweler's Supermarket because I wanted to get the Haier HU335W. What arrived was an Optima 3501. I never would have purchased from Jeweler's Supermarket had I known that they would not send me the item as described. I do own a Haier HU335W and really like it, but did not want to give an item as a gift that I had not ever tried before!

Good tool to use for regular cleaning maintenance. Certain things like copper jewelry or eye glasses will still need extra cleaning so if you're looking for something that does a real thorough job this may not be the item for you. Otherwise the sky is the limit. I dont regret buying the item, but I knew not to have high expectations for the price I paid by comparison to other cleaners.
