iSonic D2830 Ultrasonic Cleaner for Xlarge or Joined, White

I have used this sanitizing machine for over a year. It’s working 100% ; noiseless; very easy to use

I use this machine to keep my retainers clean and fresh. It works! I love it! I brought it 750 miles in the car on a road trip instead of brushing the retainers for a week.

Use it for the Invisalign trays in our family. Works well. Two complaints: (1) When it is plugged in, the unit is essentially on "stand-by" and the front LED stays on at all times. The on/off switch turns on the cleaner. (2) The timer can only be set for 180, 280, 380 and 480 seconds.

This unit is really, really nice. I showed it to my dentist who claimed it was "as good" as the unit they use to clean appliances. Cleans well - add a denture tablet and you have a great system. My only recommendation is to create a removable vessel for ease of cleaning and filling.

I have been using for two weeks now and I'm still trying to get some of the material off my dental appliance.It is preventing any new material build up, but I was expecting it to work better. On a side note, it did a good job on cleaning my eye glasses.November 26 2017 Update - I have had the unit for over a year now. To up you, the material came off my dental appliance after about a month of use. Now the unit is starting to run (vibrate) intermittently. The timer runs, but sometimes it takes 30 seconds and at other times it takes several minutes before the unit starts to run/vibrate. I believe it will completely stop in the very near future. I tried to see what the warranty is but found nothing. If you find any warranty information, I would appreciate if you would pass it along.December 13 2017 Update - It is now a paper weight with a timer. It died.

What an excellent product and well worth the fair price. We love it. It's quiet and doesn't take up much space if left out. We use it for many things from partial plates to jewelry. I would highly recommendedthe ultrasonic!

I ordered it Jan 17. It quit working last night. I was enjoying having pristine stain free teeth until it quit after four months .

iSonic D2830 has an audible buzzing sound about as loud as my electric razor running and sitting on the counter. I tried cleaning my bite guard, but didn't notice any difference using plain water. Will return this item for a replacement and let you know if there is any difference.UPDATE: First, returns are not allowed on this product even though this is Amazon Prime so I dropped the rating by one star (originally 3 stars); however, Amazon does take care of their Prime customers and sent me a replacement unit. Second, the replacement is just as loud as the first one - ultrasonic means above the audible range so for this to have a loud buzzing, staticy and rattling sound is a mystery. The 2 star rating is because it still has some benefit of cleaning even though I can barely see it. It may be more effective on things that are worn more frequently such as dentures. A cleaning solution is probably required to make this more effective, but your item still needs to be followed up with a good and thorough rinse.
