Review on Enhance Your Hydration with Evernew Hydration Tube: Stay Refreshed on the Move! by Eric Cooper

I love it the only thing I don't like is the price which is ridiculous for what you get. There are similar products on the market. Two things make it exceptional: 1. There is a non-return valve in the lid. This allows the cap to be used with a smart water bottle, for example, without destroying the bottle (or sucking air back through the tube) while drinking.2. There is a suction tube that will suck water from the bottom of any container you use. This means you don't have to turn the water tank upside down to get sucked in and risk a leak.
