I’ve had a sleep guard for a year or so and my hygienist tells me to bring it on visits and they can run it through their machine. I brush it out in the mornings, so it never seems dirty, but I bring it anyway. I guess now, I don’t have to. I still do my regular brushings, but I use the machine once a week to give it that extra special cleaning. I fill it with mostly tap water then a few drops of Listerine and the guard comes out still clean, but also smelling better. I figure if you can’t see the germs, the smell test may be an indication. Also, had a learning lesson because the instruction manual said not to use distilled water. I had to Google it, but I guess distilled or deionized water can leach some metallic ions. Weird! Pros: Easy to use and clean, came with a cleaning cloth Cons: None

I have been typically using a soft toothbrush to clean off the retainer I use each night every morning. However, even while doing that, over time, there is build up. I usually have to scrap off the crevices gently and that takes time. I got this ultrasonic cleaner with reasonable expectations and they have all been exceeded. The first time using this, my retainers didn’t seem that much cleaner. However, after the second or third time, I think the long-standing gunk on them finally got removed from this little machine. Since then, my retainers look and feel like new. Because they feel new, they fit like a glove again. Excellent product!

I was very excited for this. I have been wanting one so I just had to try. . .it was okay. My jewelry was not sparkling clean though. I thought this would save me from the fear of dropping something while cleaning but I’d rather just deal with it. While this did clean the jewelry, it does not clean the tight areas underneath the diamonds. I have come to the conclusion that it is best to just use the brush and cleaning solution.

It's small and it works. Great for cleaning small things like coins, rings, etc. Also good for cleaning small resin printed parts.

This ultrasonic jewelry cleaner performed exceptionally well, providing us with great results! It was easy to use, and we got a deep cleaning on our wedding rings, removing old paint, grease and dirt from all of the tiny crevices. It is practically silent when it runs. It also did a great job on my glasses. I like the fact that it has two cleaning modes and automatic operation. I think that this cleaner is incredibly user-friendly, requiring just tap water to operate and stopping automatically when done. Moreover, the jewelry cleaner is convenient to use on a variety of small items around our house. All in all a great find.

This is easy to use and the dire tions are clear! It works great for my two retainers. I am so happy to bc e bc able to clean them with this because they do get dirty and leaning at the dentist every six months is not enough! I have to wear my retainers nightly, so I believe this is helping me save my investment in the retainers.

This ultrasonic jewelry cleaner really works. It's simple to use and almost whisper quiet. You simply add water, or water mixed with jewelry cleaner, and push a button. It cycles off when complete. So far I've cleaned Sterling silver necklaces, stainless steel necklaces, tungsten and abalone rings, and different pendants. It all comes out sparkling! I'm very impressed with this ultrasonic cleaner.

This is the best thing for cleaning dentures. It works great it doesn't take up too much counter space and so easy to use. I wish I would have found this sooner.

This is a useful cleaner. It is very compact, ideal for jewelry. It has a little basket to hold necklaces or rings, which serves to protect the interior stainless steel lining. The device is one push operation. It runs on a 5 minute run, but you can turn it off in the middle or just keep repeating until you get satisfied results. The machine is fairly quiet during operating. Other than the motor, the only noise coming from it is the occasional metal clunking noise, presumably due to the ring I was testing the device with hitting the liner. While it is on, there is very little vibration in the device. I put my hand on it, and it is very stable. The ring that I tried with had a lot of detailing on the band. It's an old ring, where it had developed a dull finish. After one run, there wasn't much visible debris in the water. While wiping it down with the paper towel after, there wasn't any grim or dirt that I could see as well. But the ring did seem to have some shine back into it. Overall this is a pretty good product. It is well made, and very easy to use. It seems to work. Anyone looking to renew their jewelry can give this a try.

I originally got this to use for my dentures but ended up also using it for me and my wife's rings and necklaces. The packaging was professional and appropriate for the product. The product itself was packaged well and was well protected in the box. Unpackaging went well and all the components were present. After a brief read of the instructions, I decided to try it out on my rings in just water and a drop of dish soap. I was pleasantly surprised that I could see that the rings were shinier! Then I tried it on my dentures (full upper and lower) along with a cleaning tablet. The results were also as expected with dentures that looked brighter. My only issue - be it a small one - was that my dentures were not fully submerged as the water reservoir was not quite deep enough. This simply meant that I ended up flipping the dentures over and running the ultrasonic cleaner through another cycle. Overall it was a great find and will be used often!
