“Very disappointed. Leaks all the time. ”

We purchased two and they just leak all the time. When you drink water pours out from around the rim. Even when not in use it leaks from the rim at the slightest movement.

“Just the ticket”

Works fine for me... enough water without weight. Perhaps I’ve been lucky but unless you fill it to the brim and shake it it doesn’t leak.

I bought one of these after discovering them on the Water-to-Go pages. I don't go out walking without it now! I do a bit of rambling on the South Downs which has little or no natural water so I was relying on the taps provided at a few places, and lugging 2 litre bottles around! Now I can top up from horse troughs and the few streams, dew ponds I come across without worrying about it! Saves a fair bit of weight in my pack too.
