I bought O2 Max which, on its product page says it is 5 3/4 in circumference and 2 1/4 in diameter...BUT then I checked out the Lone Star product page, which says it is 5 3/4 circumference and 1 7/8 in diameter...
Wait. What? That's where I'm lost. Can someone explain this to me? Same circumference different diameter.
