i had low expectations for this item. have been keeping the butter on the counter in one of those plastic rectangular dishes for years now. it was ok, but very unattractive and messy.
knew about this type of crocks and always wanted to try it, but was skeptical that it would work right. So, i had a gift card and got it.
it holds just one stick of butter. i left the stick outside until it completely softened up and used a butter knife to pack it in the crock. the butter was so soft that i thought when i flip it over it would slide out, but no....nothing happened when i flipped it over.
put .5 cups of water in the dish, closed the lid and have been using it for 3 weeks now. I absolutely love it. the butter has never slid or even moved just a little bit towards the water. the temps have been in the high 80's, even 100's outside, so it's not that the butter has seen just cold temps and that's why it stays put.
in short, i'd get it again any day. would highly recommend it. love the modern look too.
if they make one for 2 sticks of butter, i'd get it in a second. but i still love this one.
11/13/11 update - still use it and still love it. wish it would hold more butter. would buy it again without hesitation
