I like the way they are put together, especially the way the trocar tip screws on over the top to hold it all together. I have NEVER had one come apart. I' m absolutely confident in the strength and accuracy of my MUZZY heads. As for price the MUZZY' s are the same price as a Thunderhead/Steelforce/WASP/Barrie(RM)/Rocket . So where a price issue comes from I don' t know. I can get a 6 pack of MUZZY heads for around $30-35 tops, same as the others mentioned. And the other heads aren' t BAD 2 THE BONE TOUGH!!!
