Promising review: “I don’t travel anywhere without my lifestraw. I’ve used my straw to drink from the sink everywhere in the world and I have never once gotten sick. I used it in India, China, Thailand, Brazil, Colombia, and all over the US. I also take it with me when I go hiking or camping, but I only use it in emergencies. The straw is the perfect size to fit anywhere: luggage, backpack, purse, etc. It’s easy to use and clean. It takes a bit of time to fully dry out, but I just leave it open draining near the sink overnight before packing it up again. The first lifestraw I got in 2017 recently got blocked up and stopped working. I tried to get it to work by doing a bunch of stuff I found on the internet, but it is probably done for. I bought a new one because it is 100% worth the price and has saved me on so many occasions. It has also really helped reduce my plastic consumption since I’ve been able to drink tap or boiled tap water in many places where I would have had to buy water bottles.” —Rachel
