I actually bought mine at the CNE (for all you CANADIANS out there, you know where that is), inside one of those outdoor stalls that sell lots of stuff for discounted prices! I bought 3: Forever Fressia, a beautiful light purple colour (I really liked the name of it but when I wore this colour, I honestly saw no difference in my lips...so I gave it to my sister and it looks really nice on her!), Endless Spice, a nice reddish brown tone colour (Not that much of a difference in my lips as well but there is still a bit of colour) and my favourite which I knew from the start Forever Fuchsia, a beautiful hot pink colour that drastically changes your lips and your teeth (illusionally).
They're very easy to use and the colour payoff is amazing, but the former two, not on my lips ^.^' The packaging looks like a big fat marker and one lasts a very long time, just purchased these last summer and still going strong. Since I have 3, the scent is relatively the same, not much, if any difference between each tint. One major aspect about them is that they're definitely NOT 16HR proof, never actually gauged how long it lasts but it's not 16HR, I know that for sure, but when I do, I will update this for you beauties out there!
The big FAT CON > I don't think there's any!
