LifeStraw Water Filter

Totally sucks. I realize my review won't make any kind of impact but seriously this product is junk. It feels cheap and flimsy, you can't attach a bottke to it in any way, So it's completely useless for purifying water for future use. Meaning you can ONLY drink directly out if the puddle, you cant use it to filter some water to cook with or clean with or to serve someone else. And I used one of those water purity testers? The digital ones. Bottled water reads 0 ppm, my tap water reads 110ppm, and the tap water I forced through this device using a bag and some tape to seal it, have water that was 140 ppm. So It actually made the water worse. I tested the bags, they don't increase the ppm count in tap or in bottled water. So it had to come from the filter. I then used bottled water to rinse out the filter and even that was coming out 20ppm high. Od anyone happens to read this. Don't buy this one. It doesn't even come with storage instructions which are very important. But the peak series at least. It's worth the extra few bucks.
