Here's what customers have to say
The reviews for these products are mixed. Customers praise the excellent insulation, durability, and wide color selection. However, many report issues with the lids and caps, including leaks, difficulty removing and cleaning the gaskets, and the lids becoming loose or falling off. Some also note mold and odor problems with the lids. Despite these concerns, many loyal customers remain satisfied and continue to recommend the products for their ability to maintain drink temperature.

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.
