"I love the new replacement cap! I am so happy the company offers just the lid as an option! Especially in fun colors. My partner and I use these water bottles on the daily and take the straws with us on every camping trip or trip outside of the US. Thanks again!"
"I lost the top lid to my bottle while traveling so was pleased to know I could get a replacement"
"Exactly what I needed"
"My wife and I both bought LifeStraw stainless steel bottles for our trip to Peru. I loss my cap on Machu Picchu. When I got home I sent a note to LifeStraw and a new cap arrived in Canada at my door 2 days after they received the note. That doesn’t happen every day. Love LifeStraw."
"All good with receiving items"
"I bought LifeStraw Go Series — Insulated Stainless Steel bottle. Unfortunately, when the bottle would tip onto it's side, the lid didn't seal properly and it would leak. I contacted LifeStraw and they sent a free replacement. I was cautiously optimistic because the leaking is a periodic consumer complaint. But with the new lid, I'm good to go!"
