I love avocados and have always used the knife/spoon method for eating them.  But after a recent knife to the pit miss that almost sent me to the emergency room.....I fugured it was time to give this tool a try.  
I LOVE it, the cutting edge really does cut easily through the skin, the pit remover is so much safer and the scoop end works okay.  
The only small complaint it have is the the scoop end doesn't cut cleanly, so if I was cutting avocado for presentation, I think I will still use a knife and spoon. [This review was collected as part of a promotion.]
