I LOVE my mango pitter. No more wasted mangos in my house! What I don't like is the price tag. At $12.99 (+ tax) it is a little steep for what it is, which is a fancy apple corer.
What I love about it is the efficiency. No more waste. It slices the pit cleanly and you are left with two perfect halves. When I bought mine, it was suggested not to use small mangos.
If you love mangos, it is a great tool! and the little sucker is sharp!!
I bought the OXO version on Amazon this summer and still have mixed feelings about it. As one post reflects, small mangoes won't work but I have also found that mangoes come in many shapes; not just sizes. If the mango is a bit off balance in an upright position on your counter, it can result in a lousy slice and be careful I've cut the side of my hand twice using it.
Then I saw how Bobby Flay (who's probably cleaned a million mangoes) slices a mango using a filet knife and I've decided to go that direction. Nothing like a visual demonstration!
