I ordered 5 samples, china rain, china musk, egyptian musk, northwest rain and darkest amber. They are all very high quality scents, seem to last awhile, and they are very clean and natural smelling, not chemical-y or off-putting. The china musk I put on in the morning and smelled it all day. I definitely plan to order full sized bottles soon, but I may order more samples first just to see if there's anything I like better!
I definitely encourage folks to buy some samples first. Some of the ones I bought smelled different, but still nice, to what I expected. One of them, the china musk, I wasn't sure I liked so much smelling the vial, but it worked well with my body chemistry so I may order the full size. It was a pleasant surprise. The samples give you freedom to experiment, low risk.
