I've only tested New Haarlem once and I really enjoyed it. The only problem is I've never worn it on my neck. I have a fear that it might be too overpowering.
I have some samples of Back to Black and I love that scent. I put too much one time and I couldn't stop smelling myself. I got a little sick of it, usually when this happens I'd give up on the fragrance, but I was drawn back to BtB within a few weeks. A rare occurrence for me.
