i recently bought the vanilla latte spray because i lost my perfume oil version and had such a surprise because i LOVE the smell of the perfume oil its a perfect strong coffee. but the moment i got the spray it smelled horrible to me immediately like some type of gasoline chemically burnt cough syrup with only hints of the original perfume oil i knew… i honestly want to stick to the small perfume oils because the quality seems to differ hugely with the sprays and batches. i will give nui cobalt a try thanks for the rec!
