Works well. The straw is bigger than other bottles so you can get more out of it at once. The only downside is that I don't really trust the cap when the straw is closed. Hydroflask promises that the bottle is leak proof but the cap must be completely closed and nothing should hit the opening flap. But many people are really happy with this so it's a good product all in all.

a good addition to the drink canister, you don't have to unscrew the cap. it's also tight. good washing before use so the taste of plastic disappears.

I don't think I've even kept a cap on a bottle anymore when I got this one. Makes using it as a drinking bottle a lot easier.

The whistle cover/cap is tight and not fake. A really good purchase!
