Here's what customers have to say
The water bottles are praised for their good insulation, wide mouth, and durable build, but some customers have experienced issues with the lids and caps, such as leaks, loose gaskets, and difficulty opening and closing. While there have been a few other problems reported, many customers remain satisfied overall and appreciate the company's customer service and warranty.

Great company!
[This review was collected as part of a promotion.] My original cap cracked. Went online to buy a new one and called to confirm size. They replaced for free! Love that they did not change sizes so you could replace the lid(sI). New one is a bit tougher to screw on but fits and does not leak. I do wish they offered my original cap - it was attached to the bottle neck.

Wide Mouth Flex Cap
[This review was collected as part of a promotion.] I love this cap on my bottles especially when traveling for several reasons. I can easily drink from my bottle without having to mess with a straw. Just one twist to open & one to close and secure. Love it for both hot and cold drinks. Highly recommend.
