This product is fabulous! Easy to use, works great. Highly recommend! In fact, I sent the link to my dentist to let him know to recommend to other patients! ### ⭐⭐⭐ Water spills *by on Reviewed in the United States 4 April 2024* Pros: compact, lithium battery (no need to keep plugged in), sleek look, only takes 2.5 minutesCons: shallow so water drips out of sides when I move it to sink to empty it out, hard to start had to press power icon several times, no sound I’m used to a whirring sound so I’m secure it’s working might be a pro to others who prefer the silence (I know it’s working because the blue light turns on then shuts off when it’s done), still noticed aligners not super clean as they were with others I’ve tried maybe because it’s hard to fully immerse them in water since it’s so shallow. ### ⭐⭐⭐⭐⭐ CLEANS WELL *by on Reviewed in the United States 11 October 2023* I use this daily. It is much better than the other brands. It holds the charge and with the mirrored insides it makes a more thorough job of UV cleaning. ## Frequently Bought Together - FRESH KNIGHT UV Retainer Case | UVC Retainer Cleaner, Disinfects Cleans and Removes Odors, Mouth Guard Case, compatible for Invisalign Container (Black-UV) - Retainer Cleanser Tablets Invisalign Cleaner FSA HSA Approved Remove Odors Discoloration Stains and Plaque 4 Month Supply Denture Cleansers Retainers Mouth Guards Denture Bath Mint by M3 Naturals - Retainer Brite - Retainer Cleaner Tablets for Invisalign, Mouth Guard Cleaner, Night Guard Cleaner and More.
