Feature:
Reasonable, no frills... I use it with an mp3 player to practice, quite surprised that the tone is pretty balanced for a tiny speaker. It even gives out stereo sound if plug in with stereo input.

Quality:
Quite well built for a tiny guy... My only concern is that its made in indonesia...how's the built quality like? No idea...but I heard good Yamaha pianos are made in indonesia...i guess quality is in the brand name?

Value:
I got this from a local music store for $58...what more can I ask for?

Desirability:
Its basic...simple yet practical for people like me.

Sound:
This is an accoustic guitar amp...so for that department it meets its requirements. But trying to play with distortion may blow it a little too hard. Quit well balanced speaker.

Ease of Use:
I like it! Its light, battery powered...i can bring it to friends party/church outing and stuff like that...great outdoor tool!

Support:
To be quite honest I've don't have any complaints to them yet!

Overall:
As long as it works...I need something portable which I can store easily in my tiny room, I can't afford to fill up my room with huge amps!

Feature:
Its pr5etty basic, but everything works. Plus, its small, light, and build well. I especially like the 1/4" tripod socket on the bottom -- works with any standard camera tripod! Having a line out -- even if it is mono -- is also a nice feature. I haven't had it long enough to know how long batteries last.

Quality:
I get the sense you could drop it down a flight of stairs and it'd be fine.

Sound:
Its not terribly loud, but the two speakers are definitely an improvement on others (e.g. Pignose).

Support:
N/A

Feature:
Volume & tone. What do you want ?

Quality:
Pretty solid, the thing is tiny, I've taken it camping, no problems.

Desirability:
It's just a tiny amp, great toy, not a prize possesion. Fun to play.

Sound:
For what it is, it's good. You crank it up, and it sounds crunchy. Low it's clean. I tried some pedals on it and it was too much. Great little practice/party (without cops) amp.

Support:
N/A

Overall:
I bought it for camping & it's great!! Runs on batteries, plug the mic the guitar the MP3 into it...

Feature:
To be fair, I found this little fellow on a counter with no box, no manual, and no AC adapter. I ended up paying a lot less for it because of this status.

Quality:
This little guy, in appearances, seems pretty well made, extremely sturdy with reinforced corners, and a with a decent carrying handle. The quality is lacking only in that the speakers canot handle the volume this thing is capable of.

Value:
Again, I only paid fifty bucks for this, but it lists at $99, street/store is typically $79. Definitely not worth that much, in my view.

Desirability:
Externally, this little box appeared to be highly desirable (which is why I bought it untested). It looks great with its tough-looking exterior and stereo speakers. It easily outclasses the Pignose in appearances, anyway. Afetr plugging it in, however...

Sound:
This little box isn't god for much in the clean volume department. I purchased it intending to use it with an electric nylon-string, but ended up bringing another amp to the gig. The usable volume is almost the same as the unamplified guitar due to the fact that if cranked to maximum, the little 4" speakers sound like they are about to explode! At lower volumes the sound is decent enough, but then, what's the point of using an amplifier...?

Support:
Not applicable.

Overall:
I am going to replace the two 4" speakers with the best I can find and then see what this little box can do. I have a feeling that will make all the difference, and then I may well be quite happy with the Yamaha AA5.
