Familiarity: I've used it once or twice and have initial impressions
Not mentioned anywhere in description so wanted to add. It also is my least favorite of the 3 purist tops. Also, as with many insulated bottles, in person the colors are not as vibrant because the color comes from the inner sleeve, while the outer sleeve of the bottle isn't perfectly clear. Haven't tried them yet, so will report back on how well they keep drinks cold. But one of few bottles that are 25 oz, insulated, and not ugly.
