Bests & Worsts Reviews from Amazon

Bought for camping, I'm very glad I caught this within the return window. The picture I posted shows two cups of liquid as measured by the good ol' standard Pyrex cup I've used forever at home and a set from the dollar store. Both came up to the same level. I'm definitely disappointed that I paid more, thinking that a brand name had to be better than other manufacturers. Do NOT recommend! EDIT: To those chiming in to refute my findings, please read my reply to Pony for a more detailed explanation of how I came to the conclusions I did. If you got a cup with markings that worked, good for you. I did not.
