Good to solve a few common problems: - It doesn't leak. It doesn't leak when you drink from it or when it's closed. Even if you press it and it's closed. It's not difficult to drink from unless you're a kid. It may be difficult for a five-year-old to drink from, but a five-year-old will also be pleased with the amount that comes out when not squeezed. No, you can't suck out the water, but you knew that. All water is filtered! I repeat, everything is filtered! Holes on the edge of the filter? You are irrelevant. The top of the filter matches the tiny "rim" on the inside of the cap. Therefore, water does not pour out, but drips when tipped over. It has to pass the filter. I don't think one star reviewers understand basic design concepts. Your bottles may have leaked or had problems because they used a 2nd generation filter with a 1st generation bottle. The "holes" on the sides allow you to fill the bottle without removing the filter. The water tastes great. Make sure you follow directions and squeeze a full bottle before attempting to drink from it. My tap water tastes like disgusting creek water that has been turned into pool water. It's terrible. With this bottle it tastes like bottled water. It's really amazing. A hat won't hit you in the face unless you put it up your nose. You can pull the loop to shorten the cord to keep it from dangling. Again, this can be a problem when you are five years old. If you are looking for a personal filter bottle, buy one. It s cheap. He does what he has to. You can put ice in it. I will update if I encounter problems as described here. In the meantime, I enjoy my delicious water.
