Review (2/5): Don't last very long
When they work, they're extremely convenient. These fit easily in a pocket or purse and hold enough perfume or cologne for extended trips. Unfortunately these don't last very long. I bought 4 for a two-week trip. By the end of the trip, two had stopped spraying and leaked every time I tried to use them. Maybe they're damaged by air travel, or maybe certain scents block the nozzle, I don't know. Nonetheless, a 50% failure rate after so little use coupled with the loss of cologne that's now trapped inside these two dispensers leaves me very displeased with this product.
