Ultrasonic Retainer Cleaner, Phniti 48kHz Professional Ultrasonic Jewellery Cleaner for Retainers, Jewellery, Dentures, Mouth Guard, Aligner, Toothbrush Heads, 13OZ Portable Dental Cleaning-White

I love my gold jewellery but as you can see from my photos, my rings soon get dirt entwined between the stones or delicate designs. I usually use a jewellery cleaner, but decided to try this Ultrasonic cleaner method instead, and wow, it really works, and is so simple to use. This cleaner is probably on the smaller size, well up to 300ml capacity anyway; ideal for jewellery, not just rings; I have cleaned my bracelets, necklaces, earrings in the stainless steel tub. I just need to add enough water to cover the items, and a little soap, I used washing up liquid; plug in, and wait 5-10 minutes, remove with the tweezers provided, and then dry and polish them. Everything is sparkling clean in minutes; parts of the jewellery that had been difficult to get to, even with a small brush are now completely clean, and no harsh chemicals, great! I can actually see all the dirt particles as I open the lid; this action automatically disengaged the ultrasonic light, so perfectly safe to do. Really pleased, can now use time an time again, so will save money on chemical cleaning products in future; safe, very effective, delighted.

Worked well until 2 months then broke. Then tried for refund or replacement but never got any reply! Product could be really good value for money and design if it didn’t die on me! :(

I didn't really expect this "cheap" cleaner to do as well as the much more expensive ones available, but I didn't want to spend the money for the branded versions. It's fabulous! I use it to clean my invisiline retainer and they went from cloudy (even though they get brushed every day) to being clear again. I didn't add any additional cleaner, just used water. Really pleased! My only ask is to make one with a bathroom compatible plug, as this needs water but has to live in the bedroom for reach to a standard UK plug socket.

Worked fine when it arrived but stopped working after 5 weeks with no option to return for refund. Update - the seller sent a replacement out and refunded me too, so great customer service. Let’s hope this one last a bit longer.

Stopped working after 3 months. Made sure to not get water around the outside and stopped working Edit: they refunded the amount swiftly after the review. Great customer service

Very happy with the ultrasonic cleaner. I use it multiple times a day to clean my Invisalign aligner trays and each time you can physically see the difference before and after. Food and particles get removed easily within the 5 minute cycle and the retainers are ready to wear again. It's quiet, easy to use and works very well, great value for money.

Worked great initially for the first 6 months, then one day it overheated and completely warped my retainer so I could no longer use it and left me out of pocket, losing £100 for my retainer plus the price paid for the cleaner. This was no user error, the cleaner was used as instructed and only ran on 1 cycle. It overheated during use. Emailed the seller to resolve, as it was still within their 1 year warranty, and had no response, have been completely ignored. ***Please don’t risk wasting your money or risking losing a set of expensive retainers!!***

So bought this as a present for my son to clean his retainers. He was really pleased with it until it stopped working after 9 months of use. I have sent 2 emails to Phniti to ask about a replacement or refund and have had no response at all. This is particularly disappointing as there is no other way I can deal with this. To be fair I also bought an identical one for my daughter a couple of months before and hers has been absolutely fine.
