FRESH KNIGHTUltrasonic Retainer Cleaner, 45kHz Retainer Cleaner Machine for Denture Cleaner, Retainer Cleaner, Mouth Guard Cleaner, Night Guard Cleaner, Denture Cleaner with 200ML Dental Cleaning Pod

These are sturdy, practical cases that easily fit a standard ("Hawley") style upper retainer with room to spare. They are just slightly larger, but otherwise nearly identical to the case provided by the local orthodontist.Shopping for retainer cases on Amazon will make you crazy, so it was a big relief to get a product that had no problems and indeed seemed very well made. They are *not* glamorous but they sure are practical. The latch mechanism lines up perfectly straight, closes securely.There are two air holes in the lid (the slightly thinner half) for ventilation and to allow moisture to escape. Most likely you'd want to leave the case open to really dry completely. The bottom *might* be deep enough to "bathe" a retainer or other device in cleaner, mouthwash, or whatever. Did not try that experiment yet.Also can't comment on longterm use, wearing out or breakage as it has only been a couple of weeks. But these things really look solid, so we're not expecting any bad news. Obviously, since you get two at a time, you have a spare if one should have a problem down the road.On a unit basis these are not the cheapest cases on Amazon, not the biggest, not the smallest, not the most colorful. But we are glad for the purchase as they seem reliable and truly practical for their intended purpose, of temporary storage of a retainer in a safe place.UPDATE after two years -- if you use these a lot, open and close frequently etc. you will wear out the plastic which forms the hinge on the case. This is predictable and frankly pretty impressive, ours are not shot but the signs of plastic fatigue are there and it won't be long. If you use two and alternate between them they will last longer; if you are super lucky you might not even need the retainer all that long. Anyway I would not lower the review score, they do work as planned. Only extra comment is, you will probably want to clean them regularly because the air holes are not enough to really dry out or sanitize the interior. Still recommended.

I purchased two of these. One broke within the first week so I was able to return. The other didn't break until after the return period. The issue was that the lights stop working. Amazon told me to contact the manufacturer directly and sent me a link. After hours online speaking with Amazon about how the link sent me right back to Amazon customer service, there was no resolution and they basically washed their hands of it. So I will never get my money back for this crappy product. DO NOT BUY!!

The Fresh Knight Ultrasonic Retainer Cleaner is fantastic. It effectively cleans my retainers with the ultrasonic technology and UVC light, leaving them fresh.Pros:- **Effective Cleaning:** Removes debris, stains, and bacteria efficiently.- **Easy to Use:** Simple operation with an automatic timer.- **Compact and Portable:** Sleek design, great for home or travel.- **Versatile:** Works with various dental appliances.**Cons:**- **Noise Level:** Produces a noticeable hum, but not too loud.Overall, this cleaner exceeds my expectations and keeps my dental appliances in top condition. Highly recommend!

The media could not be loaded. I love my fresh knight cleaner. It cleans amazingly and quickly. Only 5 minutes and you can continue on your day. You can be cleaning your dentures, invisalines, or retainers while brushing your teeth with the sonic fresh ultrasonic cleaning device. The ultraviolet uv-c lights cleans your teeth accessories without damaging it. You can even put a little soap in the sonic fresh for a deeper clean. It has to be gentle soap of course. The lights signals when it's starting and finishes. Its safe to use because it automatically shuts off the ultraviolet light once the top is open and continues to clean when you closes it. It buzzes when in use and you can see the bubbles foaming for that extra clean.

Amazing product works great and very convenient by fitting into a corner in our bathroom

While this product does clean your retainers and does a great job at that, it is very loud and the UV lights stop working after like 2-3 weeks. I went through two units as well. The first one I had for about a month and then the second one had the same issue. I am trying to get a refund on the second one as well. I tried it twice and was not happy with the product overall. The price is not the best as well. My sister came home with one half the price and it worked so much better!

For 2 this is such a great price!The retainer case size is great and it can fit ANY mouth guard or retainer including my very bulky shock doctor and anything smaller. Including my SD Nano and even my night guard retainers, without anything falling out like the shock doctor case.The case is a great size to hold anything. It is well vented on top, with 2 holes while fully enclosed keeping your guard protected and clean. You can attach a strap (not included) to the holes on the front of the case where you open - if you want to carry it that way. I just keep it in my bag.Sturdy well made material. Case opens and closes with ease. Stays closed when it should. Opens easily when you need it. Can’t say the same for my SD which is awkward especially when opening.I was so happy to find this great product after overpaying for a shock doctor case. I bought the shock doctor case and it was a bust barely usable for most retainers and mouth guards. It was the same price but with only 1 case and several design flaws. For SD there is a huge gap in the front which means smaller mouth guards and retainers can fall out or poke out half way with the large gap (nano). Not to mention other things like loose change and powder can get in. I’ve retired the overpriced shock doctor case for these great cases. Still love my SD mouth guards but for travel, cleanliness and portability I trust these retainer cases.

Up light quit working

Me gusto, el pastico se siente duro. Pero siento que es algo caro, tal vez unos $50 menos seria una excelente relación calidad-precio

Se ven resistentes, se ven de buena calidad y cumplen su función. El precio me parece un poco elevado.
