OVERALL OPINION

How long have you been using it?
One week to play around (given the price)

Which feature do you like the most / the least?
No lows and it has a big dip in the mids. After some modifications it starts to get interesting, but you can't get much out of the mic.

Did you try any of other models before buying this one? Yes, almost all prestigious models you can find in big recording studios

How would you rate its value for money? You get what you pay for
Based on your experience, would you buy this product again? ... Yes, to play around!
