I got the pillow spray and (to me) the lavender was very subtle, certainly didn't jump out and all together a very relaxing smell which I was very pleased with after the first use. I will see how it goes and if it does eventually get annoying!
I also got the less stress roller ball which was lovely, does clear your head as the presenter mentioned but not a strong Vick way, and doesn't linger for ages like a perfume. I used this during the day but it would be good for bed if you wanted to dose off with the smell but not have it lingering all night; the two products are different.
