Review on Mziart Portable Silicone Bottles Containers: Travel-Friendly Must-Haves for Convenience and Hygiene by Tim Reimann

Bought them for what most people buy them for, put travel liquids in. I figured that worst case scenario they might leak in flight or something. But I put some jojoba oil in one and some shampoo in the other and just sat on the counter (not even on my flight!) and they started pouring out of the lid! I find the small rubber seal on the lid does not press enough against the hole when the lid is closed. I squeeze as hard as I can so I know the lid is as close as possible. I mean if you can't even put them on the counter the way they're supposed to without leaking then no I don't recommend this product. That's why there is a star. If there might have been other problems during the flight, that's a different matter as many containers can leak with changes in pressure. It licks, just sits and does nothing. No bueno.
