“The Sonic Spa Pro works amazingly well. My Invisalign retainers are crystal clear again. My boyfriend used to clean his dingy decade old nightguard,and couldn't believe how clean it became. So far, a worthy investment.”
“I started using the Spa Pro about 2 weeks ago and WOW what a difference in how clean my night guard is! I can’t believe how dirty it really was before I got this! eek”
“My son's retainer had a white film that would not go away even with brushing. One time in the Sonic Spa and it came out completely see through, very clean! We were amazed.”
