In good condition and good working order.

Description below is from the Drum-tech website:

The drum-tec pro series supports high-end features like position-sensing (with Roland TD-12/20/25/30/50 sound modules) as well as complete dual-triggering on the toms.

Made in Germany: The entire series is assembled by hand to meet our incredibly high quality demands.
The drum-tec pro series comes with drum-tec triple-ply real feel mesh heads! They are incredibly authentic to play on, have the best trigger support and are extremely durable. (Note: The bass drum has a real feel trigger system where the beater actually sinks in to the head. This works even better with the 2-ply design series, which is why this is what's mounted on the bass)
The drum-tec pro series will fit you like a glove: It is not just a perfectly built e-drum.

The pro series also feels like the big drum-set it is with the dimensions, stage-presence and visual appeal of an acoustic set.
