I bought this unit to upgrade from my Akai LPD8. Which has served me well for the most part, but is limited and has now started to mis-trigger on one pad. I also wanted more pads for variety in my 'finger drum' playing.
The unit is solid looking and feeling, doesn't move around on a table top when you play due to good quality rubberized feet.
The pads themselves feel good and are much more responsive than the LPD8. You can get a nice amount of dynamics in the sensitivity. Overall it feels good. The 6 endless rotaries feel good, but I don't really plan to use them, so I can't elaborate much there.
The configuration software that comes with the unit is OK and does the job. I was quickly able to set up some custom banks that worked almost instantly with EZDrummer and in cubase.
One problem I had was that after-touch was on and set to trigger on the the MIDI channel. This meant that I was often choking hits in an undesired fashion (mostly noticeable on cymbals). So this is something to look into first. Either turn it off on each pad or rig it so that the cymbals that you want to choke are on a different MIDI channel to the rest of the kit. I find it a bit fiddly during playing to use after-touch to choke cymbals anyway, so I just turned it off and put any chokes I wanted in editing.
Generally the feel is nice to play and doesn't tire your hands so much as say the LPD8 which really needs more of a whack on the pads sometimes to get them to trigger.
So, I don't have much else to say really. This is a simple, solid unit that will do the job for fairly advanced 'finger drumming' or sample triggering
