This Review Title is Works great short term and the content is: This is great for whitening for a specific occasion. My teeth were super white, looked great in photos, received lots of compliments. It doesn't last longterm though, so I wouldn't use it for permanent whitening or maintenance. I have permanent retainers on my teeth, so it's difficult to get strips to stick. This was easy to use with permanent retainers, and you can pop in the goo+tray and watch TV or whatever. I did like the hands-free part, but it does get annoying to have to rinse and reapply the gel every 8 minutes. I would use again in a pinch but would prefer professional whitening longterm though it is the pricier option..There are other information for this review, one is This reviewer did purchase it and the other is 12 people think this review is helpful.
