Patternmaster Anaconda Stiker Tube?

[TheSportsman]

Anyone have any feedback on this choke?  Looks to be a well made tube.  I looked at one today for a Benelli/Beretta Mobile in a .670 constriction.  Anyone shot any of the Anaconda series chokes?

I have shot the full (not at turkeys) in my A400 Xtreme. The patterns are consistent and even.
