After many emails I took the plunge and ordered two packs. The heads are 100% American made which I like. They have a lifetime guarantee with proof of purchase no questions asked just send it back if it fails and they will send a new one. They come in a nice wooden box and are super sharp and can be re sharpened.
They fly very well for myself and everyone that has tested them.
They are a new company out of Colorado. Yes the price point is high and probably not for everyone. Here is a link with all the specs. I anxious to put these heads to work.
