"Does exactly what it is advertised to do and does it very very well."

Feature:
just fine for the price; you want more, you spend more

Quality:
so far, the quality is top notch for a controller in this price range

Value:
terrific value

Desirability:
the o2 looks great and the thin profile does make it highly portable

Sound:
does not apply since this is a midi controller

Ease of Use:
very easy to use overall

Support:
does not apply; i never had to use m-audio cust. support

Overall:
you must understand that this product does everything advertised. yes, the keys arent weighted or full stroke, but that's why its very portable (this is the way it was made; meant for). but its also very fun to play with and you get used to the key strokes and such. please review a product understanding the end market for such an item. for instance, dont bash a model because it is lacking in features that a more expensive item possesses, etc...

M-Audio O2 USB Keyboard Customer Review

Feature:
I wish the modulation and the pitch bend were actually a wheel rather than the weird pressure button it is. It's hard to make exact modulation/pitch bend changes. Also, why does it not come with an AC adapter?! Other than that, every thing works really well.

Quality:
Very sturdy and also pretty light. Very thin as well.

Value:
At the current super discounted price, its a very good value.

Desirability:
It looks a whole lot better than the Oxygen...as in, it doesn't look like a toy. The silver colors make it look kindof sleek.

Sound:
N/A

Ease of Use:
Just plug it in and use it, pretty simple.

Support:
Never needed any support.

Description
Docs
The M-Audio O2 follows in the footsteps of the mobile USB MIDI controller that started it all -- the Oxygen8.

You get 25 full-size, half-action, velocity-sensitive keys, along with eight fully assignable knobs, 8 fully assignable buttons and other real-time control features for performance and programming. One simple USB connection serves as both a MIDI interface and bus power source. Class compliance with Windows XP and Mac OS X means that you can get down to business without even installing any drivers.
