FLAWED DESIGN - LEAKS
"This, as a travel-specific product, is hot garbage. DO NOT BUY IF YOU FLY. The first time the shampoo lid leaked - shame on me. The second, third, fourth, fifth time - shame on Ouai. I am sick and tired of not only wasting product, but having to wipe, wash, rinse, wipe, wash, rinse, repeat, repeat, repeat EVERY TIME I fly. I am a business traveller who always has to check a bag - the lid on this bottle is not robust enough to survive baggage handling. Every other product in my toiletry kit manages to stay closed, except this shampoo. I have to take everything out and wipe the shampoo goo off my suitcase and other products both at the hotel (leaked on my way TO my meeting) and when I get home (leaked on my way home FROM my meeting). At first I thought it was user error (me), but after multiple double and triple checks that I snapped the shampoo lid closed before packing up, I have to say that this is 100% a design flaw and to only use this travel bottle if you are on a weekend trip via car. It will absolutely NOT stand up to airplane travel."
