SQEVO Squonk Bottle
It's not the best, but it's not the worst either. Upside: fits snugly in the Sqevo, so far no leaking at all! Downside: Is easy to screw the cap on too tightly so finger tight only. also juice comes out at the slightest touch when not installed. Wish there were some other options that fit, like a silky.
Purchased for spare.
