I like this mike. For voice overs it is much better than all others that I have tried. The only fault is that the design of the mike lets it flop down from the upright holder. Poor design there. [Same thing on both Nessies that I have used.] But it works and works very well.
Just wanted to clarify something I was not aware of before purchasing. The headphone-out on the back is the best feature since it allows zero-latency monitoring. Furthermore, if you switch the audio output on your mac to the mic, you'll get the monitor plus any audio output from your computer. This lets you video chat while hearing yourself. I'm not sure why this is so fantastic but it somehow is.
The negatives would be the size (hard to avoid since it needs to be elevated) and also the materials. I'd love this to be aluminum or another metal even if were 2x the price. That said, it still looks solid and will probably last a long while. Another negative is its ability to pick up voice from afar - this might be inherent in the way sound works but when you are right up close to the mic the detail is about 5x as opposed to 6" away. The shock mount is also not all it is cracked up to be. Take these negatives with a grain of salt since there are many more positives than negatives.
Overall it is solid and I'd not hesitate to purchase it again. Making a mic with professional-grade construction with the same consumer-driven features would be the icing on the cake. Still the best desktop mic I've used and I'd highly recommend.
