Horrible experience
I pre-ordered 4 of these, hoping they would keep mineral rings from building up on my toilets at the water line. I have 4 Toto toilets with special ceramic coating, so they stay pretty clean already, except for the ring. I also added on a year of the Shine Unlimited service to get replacement pods. It took a long time to receive the units, thanks to COVID impacts (understandable), but when I did, I installed the 4 unils slowly to see how they worked. The first issue I had was with setup. Setting up the units seemed to be very buggy and fraught with issues connecting to Wi-Fi. Even after connected to Wi-Fi, the units would often not sync well with the app. I.e., the status reported by the app clearly didn't match the status of the unit I could see. In terms of toilet cleaning, I honestly did not notice much of a difference with using just 1 pod. On the next cycle, I tried 3 pods, but also did not notice much of a difference. I then ran out of pods, and ordered more, but the order was never fulfilled. I then went back to the app to try again, but the app says "Coming Soon" for all of the options under Refresh. If I click "Support", I get a screen that says, "Contact Us" at top, but is otherwise blank. I tried sending email to support, and I get an automatic response back saying that someone will get back to me, but they never do. Thus far, these have been a complete waste of money and time. Adding to my concern, I received a communication saying that Shine Bathroom, LLC, would be assuming all debts of Shine Bathroom, Inc. Having had a little experience myself with start-ups making products, I have heard that LLCs are preferred when making and selling physical products.
