It appears that 512 audio is the "podcast/streaming" division of Warm Audio. A quick look at the their products shows 2 XLR mics, 2 USB mics and an audio interface. Comparable products would be the Rode Procaster, Shure M7XT and the EV RE320, which is strongly resembles. I've never heard one. One thing I noticed is that they mention that it's tuned for "voice". I can't find any info on the frequency response so I would take that with a grain of salt. Sounds like marketing speak to me.
I guess the first question is what all are you planning to do with it? Run a podcast or Youtube channel? How are you planning to hook it up? Do you have an audio interface?
Just an FYI, Musicians Friend and B&H Photo have it for $150.

Ray, I just went back to your earlier posts, and your Youtube channel. Based on that, I don't think I would go down the Limelight road. There are lots of other options out there with more proven track records. And it's not because I have anything against Warm Audio. I've got a Warm 47Jr and it's a really nice mic. Its just a bit of an unknown quantity, and I would rather get a few opinions before I sink that kind of money into a mic.
