They obviously fly well but they don't seem to be a popular choice. They seemed to be talked about for awhile on different forums as they really tried to hype 'em up, they even gave many of us FREE heads just to get us to talk about 'em. However,I personally found the blade tips a bit delicate. They'd bend and dull so easily in any test media I fired them into.

For my money there are MUCH better b-heads available but good luck with your choice. Surely you can gather some positive feedback here.
