We invented this tool from scratch last year and now here is our new version! The ELITE. These upgrades aren't just skin deep... We've added six ball bearings to the diameter adjustment system. Less friction= tighter tolerances= even more accuracy and less flex. Added feel of the diameter detents is bonus improvement! 
 
We've also added and aluminium suction foot mount at the bottom of the tool for added stiffness and strength.
 
Last and probably least, but... The gold engraving doesn't really hurt the look of it!

Available now for pre- order with deliveries scheduled for the beginning of April
