Aotuda 45kHz Retainer Cleaner Machine

I have Invisalign and I been wearing the retainer for 3 years, I have always worried about how i would get it cleaner and keep it cleaner as its something we essentially have to unfortunately wear for a life time to avoid teeth from shifting back out of place. Which obviously means we need a good reliably way to truly clean it not only to be clean and feel great but also the bacteria on these things can harbor on your enamel overnight and really be an issue especially for cavity prone teeth like mine. OMG this thing I tried it only once the first time and WITHOUT solution (that was also big to me one of the things I was hoping with this is for it to be cost effective so that I wont buy anything everytime like i was with the solution tablets which btw was barely doing anything and this thing first cycle came out like crystal clear!!! wow now I cringe at how dirty it was and how often I was using that not knowing better. Also what a wonderful price compared to the other brand on facebook and on social media thats like 100 bucks. Thank you company I am happy!!!!
