I use one. I like it. The only thing I don' t like about it is the spring loaded bottom. If you' re not carefull the thing will unlock and throw the arms up....not a problem unless you have three fletchings with glue ready to go. I get a very consitent and nice fletching job from mine. A lot of guys talk big about the Bitzenburger, but a friend has one and I' m not overly impressed with it. Nothing wrong with it, but I don' t see how it' s any better or worse than the Arizona.
