Mixes real well, works perfect for a bachelor thats new to cooking. like it. Might glue the o-ring in place but it works pretty well, fun too. the o-ring that seals the liquid in the shaker falls out. You must make sure its in place right before you close it, it likes to jump out, i also tried to crush 3 cloves of garlic at once and it wouldn't do it... i guess it didn't leave enough room for the ball to move enough.
