Feature:
The most feasible features are ALL included the Training, Chain and Program. All are invaluable if utilize, which will aid in develope your skill. I wish the unit would have been mountable. Not the best design, like one viewer stated it does feel cheap.

Quality:
Cheap built. The worst for me is not designed to mount.

Value:
I bought; however; 69.99 would be a price.

Desirability:
This is s practical unit...

Sound:
The sound is not bad, the owner's manual stated the unit was designed for high volume thru use of headphones (which I take the sound was catered to better produced sound with headphone output).

Ease of Use:
I have used it thru my P.A. system and Roland TD20, not bad at all for practice situation. The manual was clean cut (if read). This really is a practical unit for all purpose practice rudiments, phrasing, subdiving, counting and reading music. I use it for both my instruments Drums and Bass practice.

Support:
Have not need to contact the manufactor.

Overall:
I handle it with TLC...

Feature:
Not bad, but for the price, I would expect the thing to turn itself off after a brief period of non-use to save the batteries. Speaking of which, I consider 4 AAA batteries much less convenient that 1 single 9v.

Quality:
Feels cheap to me.

Sound:
The sound coming out of the speaker is distorted.
