Not remotely A/V related, so I'll put it here.
I'm trying out my first pair of the new Crest Advanced Seal Whitestrips (yep, that's what UPS delivered), and I like them so far. The biggest con to Whitestrips for me was that they didn't adhere very well - they kept wanting to slip off. Target brand strips (which are identical to the Rembrandt strips that I tried, but cheaper and a different color) stick on fantastically well, but they have a very thick and stiff backing material and are obvious (it's like you're wearing a mouthguard, IMO). These new Advanced Seal strips are thin like the original Whitestrips, but they stick on just as well at the Target strips. Fantastic, I think. I can talk normally, and they haven't slipped one bit.
The one con is that Crest has gone back to a smaller size strip for the bottom teeth, like what they originally had for Whitestrips back around 2000. The strip is too small to cover all of the visible front teeth. They did increase the size of those strips later on, so hopefully they'll do the same with this line.
Anyway, I had some time until I was supposed to take these off - but that time has come.
