I bought the 50ml with atomizer. It was worth it to me. This is very special stuff. The manner in which I use frags means this will last years. I appreciate the price break on a flacon, but prefer smaller 50ml size. There were a few flacons left when I bought it.
I like male rose scents, entrusted Dullah's early enthusiastic reviews and did blind buy it, But, I would encourage you sample. I have a large variety of frags, most of which I really like a lot. Windsor just one more of them for certain purposes.
If you're looking for a frag you'll wear a lot, you should sample it first. It is perfume art, no doubt, but it's wearability will vary from person to person. It is not for everyone, and I don't mean that in some sort of elitist way. It's an odd, aloof and austere scent.
