We've sold lots of them.  They just work.  Like any hot rod, they can take a little finesse to get them set just right, but I've never seen a situation, that it was made for, that it couldn't be set to impress.  The biggest concern has always been the shallow placement.  We do around 30 demos a year and consider a demo to be 2 tanks of NH3.  This gives us the opportunity to run beside many shank machines in a strip in the field.  I've never heard anyone complain about a drag in the 2510H area.  You could not be impressed with it if,  1) You want to run <6/6.5 mph,  2) You want to put NH3 >6" deep, or  3) You want to till the soil with the NH3 bar.  Otherwise, enjoy!
