I, finally, received the samples by post.
It's a great free sample if 'm honest - nicely packaged and you get 3 satchels.
You can get 2 uses out of 1 satchel so pretty much 1 week worth - enough to properly try the product.
Personally, I love it!
I'm loving it as a tinted moisturiser; a BB Cream is supposed to 'do more' and on that I'm not sure if you get all the possible benefits, promised by this type of products but as a tinted moisturiser is perfect. Nice light consistency, easy to apply and literally sinks into my skin. Also, the light shade is a good match for me (it reminds me of No7 Dual Protection Tinted Moisturiser SPF15, which I used a couple of years ago, but it's even a better match colour-wise).
Staying power is also very acceptable and I didn't even have to set it.
It's definitely a good budget buy - have you try it yet?
