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.

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 recommended the ultrasonic!

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.

Does not seem to cleans well as the original model which finally died after years of use.

They work really well until they fail. I've now had three of these at around the 1-1/2 year mark start to intermittently make far less noise and then consistently make a lot less noise with far less cleaning power.
