Whizzer Strips

I got them in around december or november. They were reduced from €29.99 to €15.99 in my local chemist. I had braces for two years and got them off the end of September. I wanted to try whiten my teeth because they got kind of yellow when i had braces(due to not being able to brush all of my teeth because of the metal bits).
Usage:It says to use them once every day, or twice a day, until you are happy with the results. I honestly didnt see any results. My teeth werent really yellow to begin with, but they werent very white either.
My experienceI dont really like them, as SOON as they touch your teeth they start dissolving into a goo. This means you cant re-adjust them, it starts to come off on your finger. So they are kinda hard to put on and position correctly.
Timing:It says they dissolve in 10minutes. It took at least 15-20mins for mine to dissolve. So for twenty minutes you have this gooey stuff on your teeth. Not pleasant! In the end i gave up on them. I still have half a box, so i might try them again using two every day for a week.
Overall: So to conclude; They are cheap enough, i didnt see any results, i dont like the whole gooey-ness/format of them, and it took a while for them to dissolve. Im not trying to bash the brand or anything but they really didnt do anything for me, and i was glad that i bought them on half price as i wouldnt pay €30 for them now.
