I have this in three shades, and am onto my second and third of a couple of them.
I love this product, especially as I'm a pretty busy lady most days so don't get a lot of time to reapply make-up, plus my office has glass walls so it's a bit public.
The colour stays all day, and if you apply the shine that stays until you either drink /eat it away. I tend to reapply the whole thing once a day, as I wear the dark plum and the berry colours, so they leave a very distinct line on my inner lip.
The colour range is the clincher for me, as the reds have a blue base, which I need for my skin tone. You need to have a steady hand for the darker colour application, as wobbly lines stand out a mile!
Overall this is a great product - I love it!
I was a bit sceptical about how long-wearing this would be, but I have to say if applied right this does last all day. There are so many wearable colours (and bold colours) to choose from. One end is a lipstain and the other end a gloss, which is not just to make it look shinier but it also helps the colour set and stay longer (I actually prefer it with no gloss as I like the matte look but then all bets are off about how long it wears for). If you can get it to apply evenly in one coat, you'll find it wears pretty evenly as well (with no ring around the lips by the end of the day) and I've found the tip of some of the lippies are a bit more precise than others. I highly recommend the Seductive Sienna shade, it's dark, very wearable and can suit most skin tones.
Tips: I use a lip balm first and let it settle in for 10 minutes or so before I apply the lipcolour but I've found that if my lips aren't dry, I could probably skip lipbalm
