I have been a member for 6 months and overall have had a positive experience. I have an annual subscription but even when you add the subscription cost to the product cost, I think the products are still very good value for money and I've been impressed with the quality.
Particular stars for me are the retinol range - I use this five nights a week and the difference to my skin is really noticeable - less fine lines and wrinkles and generally smoother. I also use their superdrops flash face lift with hyaraulonic acid and Uber Youth re-elastic serum in the morning and love those too. The Super Healthy Skin cream and ceramide capsules are also go-to products for me.
I haven't experimented with the make-up very much so can't really comment on that.
There is an excellent facebook group with lots of supportive and helpful women discussing how to combine different products and routines that work for them which I have found very helpful.
As I paid my subscription up front when I started I only pay out the product cost each time I order so it gives me the chance to try some things I wouldn't normally without it being too big a commitment. For example I've just added an acid in the morning to see what that does for my skin.
I only order once every few months to save on postage and have on one occasion bought some allowance off a member of the facebook group to give my spending limit a boost and stock up.
Lastly, they are big on recyclable/recycled packaging so that's another win for me.
