Customer Reviews
Good as always
I ordered another 40oz Insulated Water Bottle, black this time. It's just as good as the ones I got last year. Consistency is why I keep coming back.
Decent value, small issue
Got a Dual Pack Water Bottles (32oz) during a sale. Shipping took about 6 days to get here, which was okay. The bottles themselves are solid, keep water cold for ages. One lid felt a tiny bit stiff to open at first, but it loosened up. Good for the price.

Thinking of grabbing one of those 40oz bottles, but wondering about the lids. Are they all interchangeable if I wanted to switch between a straw and a chug lid later?
