Bests & Worsts Reviews from Amazon

these bottles were my go-to bottles for my coffee, but sadly, the lids on these bottles are not that durable. They break within 2 months of use; the snap-latch on the back cracks after 2 months. And if you don't mind that and keep on using it for another month or two, the button eventually gives out and literally fall off mid-drink. I have gone through countless new cap orders with them via directly contacting their customer service. Eventually, after dealing with the same issue with each new cap that I ordered from them, I sadly gave up on my favorite thermos bottles and decided to go with Zojirushi thermos bottles instead and have not had any problems (been using it for 6 months!)
