Feature:
Ignore the other review, this microphone doesn't even have a battery compartment - they must be confused on model numbers. Great for an area mike

Quality:
Had two for two years now used 3-4 times per week constantly moved around with no problems

Sound:
Excellent sound, very crisp

Ease of Use:
Just plug it in -

Value:
Great mic for the price -- very good, regardless of price

Desirability:
Love the small size!

Sound:
Clean sounding, without the "presence peak" that so many newer mics have. Excellent for instruments (especially fiddle and mandolin) and actually a good vocal mic!

Support:
Have not had to deal with A-T for service

Quality:
These have been thrown in a mic case without padding, smacked around with a bunch of SM57's and 58's and still they perform flawlessly. This mic has been around for a number of years and still it is a best seller. That says more about the product than anything else. Also, I am sitting here with two broken AKG Perception 150's. I bought 3 of those mics and two of them broke just hanging from a ceiling! - I should have bought Pro37's for that application as well!

Value:
It is a bit more expensive than the newer contenders which run about $30 cheaper ($130 as opposed to $100) but in my experience it is well worth the extra $30.

Desirability:
It is a practical little mic... nothing more.

Sound:
This is the best inexpensive small diaphragm condensor I have used. It has excellent feedback rejection and a strong pick-up pattern - even with distant sources. Further, it is a relatively flat frequency response where many newer small condensors have a bump around 1-4k.

Support:
Honestly, I have never needed to contact AT for this product.

Overall:
This is my go to mic.

Feature:
Battery is useless.

Quality:
Noisey and makes pops during recordings. Really disappointed.

Sound:
Noisey and occasional pops because of a poorly constructed battery compartment.

Ease of Use:
plug and play if you have a preamp for it.
