“OK I can rate this a 5 now”

“I love these things. I got a couple to try it and now I have 6. I drink and sweat a tremendous amount when I hike. I cannot carry any more water so this bottle is indispensible. I use it to fill from the smallest trickles of water and it works great. You have to squeeze it to get decent flow and you may have trouble getting the last bit from the bottle, but being able to fill frequently is key to me. I love the ease to fill it and then have good clear water right away. The bottle has held up to hard squeezing now for 6 long hikes (10+ miles) and I use it as my primary water source. The latest bottles I received were better designed to get the last drops of water and I will be using this design today. I got one for everyone in the family.”
