Feature:
it has phantom power, compressor and 3 band eq. I find the comp a bit strong, it's best to use it at small amounts. It has a fixed ratio. The eq is pretty nice, even though it does not have q selection but never needed. Quite enough for determining the general sound. With a nice mic, no hesitation.

Quality:
this unit is metal covered, quality knobs and leds. Small sized and light weighted, so easy to carry.

Value:
according to money paid, this unit totally worths. Especially if you also have a transparent preamp, this may be a nice alternative coloring preamp.

Sound:
the sound is warm enough, there's s small amount of coloration at low mid area. It's not a high end product but results are very stable. If it had much open sound i'd appreciate more, but also the money paid for is totally worth it.

Ease of Use:
Very easy to use, no need to diving into manual.

Support:
never needed a support

Overall:
Even if it is not "the best" , it gives a nice sound to your mixes. I strongly recomend for beginners. The price is acceptable for it's sound and quality. Even if you buy a better preamp in the future, you'd still want to keep this.
