Thus far, we've only tried the perfumes. However, they've been really impressive. They aren't knock-offs either. These are the genuine article, in a smaller dose than you would pay elsewhere.
Next month's essence will be Burberry Brit and it is exquisite! It has a high sillage and a longevity value to match (8-9 hours)! The essence fades and seems to change (slightly) as it ages. It's nice, though. We are extremely picky and we loved it.
ScentBird would make an excellent gift!
