I wallowed out my tip with needle nosed tweezers and now it requires much less squeezing.
Also, in other bottle news, I successfully removed the tip with those tweezers by jiggling the point into the crack then flicking out repeatedly. It flew across the room, lol, but it did come out...and I only stabbed myself with the tweezers once. And it went back in and isn't leaking because the stopper end is pretty long. So this IS potentially a reusable bottle if you have a little patience.
I mixed my watermelon with another watermelon and got the bottle cleaned and label off for one of my fave juices!!! I love the bottle.....love it!
