I've juiced grapefruits, oranges, lemons, limes. I've read in the comments it works for pomegranates. Make sure you get the tall one, the tall one is more expensive but fits a pint glass underneath it. If you get the shorter one you might find yourself juicing into a smaller glass and pouring into a taller one, just spending extra couple bucks is worth it. For sturdiness I gave it only 4 starts because sometimes if you squeeze too hard or too quick it'll tip a little. No problem for an adult, maSee full review
