I recently got a couple of these as samples from a friend of mine.
The samples work really well for me as I love playing with colours but am often too afraid to purchase the lipstick in a bold colour.

I've got a good mix of natural tones, reds and more darker (plum) shades and I must say that I really like the nice darker shades (who knew!)

I am a bit disappointed in the longevity of the lippie, I have to re-apply often during the day, it gives off on mugs and glasses very quickly and then you'll have to re-apply to get that nice finish again. It also tends to stay on my "outer" lip area (if you get what I'm saying?) yet a little bit towards the inside it goes off very quickly (so if I pout it looks like I have just an outline of colour).
It also tends to start flaking a bit towards the end of the day which, if you don't re-apply, looks really horrible.

The price isn't bad, but I've had better results from cheaper products.
I do still love Avon and the shades are really great!

The Matte look is so in season and I just love this lipstick. It goes on smooth with little or none of the cracking feeling we get from other matte lipsticks
