Does anyone have experience with Obagi Nu-Derm system?

I went for a facial today, and at the end I asked for recommendation of skin care products. Obagi Nu-Derm system was highly recommended. In fact, this was the second time Obagi was recommended to me by a facial place. Can you please let me know if you have had any experience with it? I am tempted to give it a try.

Thank you very much.
