Retainer cleaner that actually works in real life

Two weeks in and this little cordless cleaner is now a regular thing on my sink. When I first opened it there was a slight plastic smell, and it comes with a travel pouch and a small cleaning tool set, which is nice. The stainless steel tank feels pretty sturdy and the whole thing is compact enough to stick in a drawer. I wasn't sure a cordless unit could keep up with my nightly routine, but mode 2 for 10 minutes clears up the cloudiness on my old retainer way better than I expected. The 45kHz ultrasonic action plus the UV refresh really helps with odor and getting the surface clean. It's got a four level LED display that shows battery status in real time, which is helpful when you're rushing around in the morning. Charging is easy with USB-C and the 4000 mAh battery actually lasts several days of daily use on one charge. Only complaint is the lid and basket feel kinda fiddly, and the cleaning basket can be tricky to line up when your hands are wet. Value-wise it's worth the money if you travel or want something mess-free, especially since it comes as a complete kit. The travel pouch is sturdy and keeps all the little pieces from rattling around in my gym bag. Just make sure the water stays below the MAX line and charge it before a trip. Read more

Decent Price, works pretty well!

We have always wanted one of these ultrasonic cleaners for jewelry, or retainers/mouthguards, so we thought we'd give this one a try. This is overall a pretty nice product! Here's our pros/cons of it: Pros: 1. It's pretty sleek. It looks nice and feels pretty high quality. It also has a nice sized chamber for cleaning things. 2. The fact that it has a rechargeable battery is awesome. It was half charged right out of the box and we could use it right away. Seems like it will hold charge well too. 3. It actually works! We started by throwing some earrings in there and letting it run. When we pulled them out after the 5 minute cycle, they were definitely quite a bit cleaner and there was some stuff in the chamber that clearly came off the earrings. It overall made them a lot nicer and shinier. We also threw some retainers in there and a mouthguard, and those came out with less buildup as well. Nice and easy to use! Just throw things in, click the power button once or a couple times if you want a longer/different run, and you're good to go! Nice to see the UV light on and see the waves being produced too. (see pictures) 4. It's decent value for the money. There are some cheaper ones of these out there, but I'm not sure on quality. I so far don't feel cheated out of money for this. It's around average I'd say. 5. Came with lots of tools/accessories - this came with a carrying case, a small brush, a tweezers to get things out, and a little hook for grabbing things, which is nice and convenient. There's also some sort of cylinder and stick - no idea what that's for...but neat I guess. Cons: 1. I wish it had more clear instructions - mostly on what the mystery tool is. I haven't found anything that explains that. 2. The power button is a little annoying. It's SO easy to accidentally turn on, which the instructions say is bad to run dry. All you have to do is touch the power button for 2 seconds and it's on and starts running. I have accidentally turned it on like 4 times in the first half hour of unboxing and taking pictures. I'd rather it be just a button. 3. I'm not entirely sure what the tray is for. I guess just carrying things? It doesn't sit low enough to sit things in the water, so you can't have like 2 layers running at the same time. That would have been nice. 4. I don't consider this a huge negative, more of a note, but the power cord is a little short (only about 12 inches long) and it doesn't come with a USB-A brick. I have extras, but hopefully this is helpful to some people. 5. The mirror has a small flaw in it (see pictures). It's a cheap mirror and I doubt we'll use it, but thought I'd note it. 6. Ours has an interesting sound. May be annoying to some people. But we aren't too bothered by it. Hopefully that's a normal thing. Unfortunately Amazon was not letting me upload videos to so you could hear it. But it has a definite buzzing sound. Overall, I think this is a nice ultrasonic cleaner! It was easy to see that it works fairly well right away. It is a good price, comes with all the tools you need, and the fact that it has a rechargeable battery is pretty cool. We're happy with it. The negatives are pretty minimal overall, and won't really affect our use of it, so not worth taking a star off in our opinion. Pictures: 1. All items in box 2. UV Light works! Also note the display with the second countdown, power button on right, and then the battery level on left. 3. Earrings in before run 4. Earrings during cycle. Note the small waves in the water. 5. Debris left behind from earrings after cycle - it does clean! Read more

Works really well!

I have a mouthguard that I use for teeth grinding and it gets gross after a short use. It smells and has crud buildup over time and I have to soak it in a cleaning solution every other night. This product cleaned my mouthguard in under 10 minutes using different cleaning modes. It's easy to use and wireless so you don't need another bathroom device taking up precious countertop space. I keep this on my nightstand and use it frequently. When cleaning is done, you get an alert beep. It's a high quality product and a somewhat compact design where you can take it when you travel. There's lots of additional accessories but I just use the device itself and the tray. After each use, I'm surprised at the amount of floating junk that shows up in the water. It cleans my mouthguard much better than just soaking my guard in a solution for 5 minutes. This is a great value for what you get. Overall, I'm very happy with it and would recommend to others.

Tiny But Powerful

It really works! I’ve used other ultrasonic cleaners for my retainers but this one works way better! It’s small but it packs a punch! I used mode 2 to clean my unbrushed retainers and the water was super murky when I pulled them out after the cycle. I brushed them and ran another cycle on mode 2 and they’re even better. My retainers are 10 years old so it’s quite impressive. No damage to the retainer whatsoever. Comes half charged. I like that you can charge it and use it cordless. It comes with a bunch of little accessories like tiny tongs/tweezers, brush, protective bag, etc. The device is a little larger than my palm so quite compact but big enough to fit my retainers in without overlapping. I only used plain water but am curious about trying it with the dissolvable tablet retainer cleaner. There are not really clear instructions about using it with a cleaning agent Read more

Nice ultrasonic cleaner for jewelry

I got this to clean our jewelry. It's a good size and can clean several pieces at once. I like that it has a rechargeable battery inside so it doesn't have to stay plugged in. It is easy to use and has several modes for cleaning. It isn't as powerful as a commercial unit but great for home use. I usually run several cleaning cycles in a row and you can see the black dirt and grit in the water. It works well and is priced fair! Read more
