First. I bought it directly from the manufacturer, so I don't have a "verified" purchase on it. I went to the manufacturer because I wanted to try a smaller set (1 month set) that Revain didn't offer when I bought it.1. A "monthly supply" is actually only a WEEKLY supply - the "effect" should last for a month. Misleading, to say the least. I have to say it's ONE WEEK. I took pictures that show NO difference to my eye. A NOTICE. I used it exactly as described in the instructions. ALSO. My front top 4 teeth are porcelain onlays from 15 years ago. This system is believed to be safe and effective for both dental treatment and natural teeth. I have not seen.3. It's a messy, two-step process. Tube #1 is a super stain remover and then tube #2 which you apply after using tube #1. The photo I've attached was after tube #2. The tubes themselves were a huge pain. In most cases, they were extremely difficult to open, even when "gently folded" as instructed. I believe I had ONE tube that actually burst open without much effort causing the tampon to move making the treatment difficult to apply. They also include a tube to use when you're out and when you eat or drink anything that could potentially stain. It has a soft brush like tip.4. Initially the solution had no effect on me, but after 7 days my gums became very sensitive. I have a sonic toothbrush with generic brand toothpaste and brushed my teeth before every morning routine. Apparently it's some kind of peroxide formula. You can try this. A little mint or something mixed. But the aroma of peroxide does not hide.6. After all, the pictures don't lie. I don't see any improvement at all. Photo #1 before. February 17th. Photo number 2 from February 23. I would love to see the rest of the photos when considering a purchase. Hope that helps. In my opinion this is a waste of time and money. I've added photos so you can make your own choice. I don't hesitate to update my reviews when new information seems useful, but to be honest I won't be buying from either the manufacturer or Revain again.
