I would describe it as warm and detailed without being hyped in the trebles, maybe a little toned down so you might pull it up in post in some cases. Picks up a lot of low end.
I can see why some people might not like the stereo field, it's very wide.
I often adjust it to 70-80% L/R finding that sounds a little more natural to my ears.
People have different ears, and will have different preferences on this.
Not really something I consider an issue as it's easy to adjust stereo spread in any DAW, or often on the recorder itself.
I'm using it with a MixPre-6, and it's a very quiet microphone, I'm getting great recordings with lot of detail and clean sound.
The extras aren't anything to write home about.
Especially the clip is very basic and the adapter is plastic, not metal, which seems like odd cost cutting on something prone to wear and tear (and likely doesn't cost much to begin with).
The padded bag isn't too bad, it comes with a 5M cable which is convenient, and the foam is nice to have.
It's fairly front heavy for its size, so keep that in mind if looking for wind protection.
Overall, it's a nice mic and it's a lot easier than dual microphones on a stereo bar for going out doing field recording.
