It's a multipattern condenser with a U87 inspired headbasket. It's a bit expensive, like twice what an iSK BM-600 costs. The only advantage I can think of is that if you care about where the pattern switch is, it's on the front, though you could always flip the capsule or wires around. The iSK/Devine BM-600 comes with quality components inside too.

Read the description carefully. It only describes one pattern. And no switch. Ask them specifically about the switch/switch holes. I got a nice looking fake switchless u87 type for free because I had screen shots of their “yes” and screen shots of the photos in the ad, thinking I was getting an amazing deal if true. But it wasn’t and Alipay ruled in my favor.
Here is yours

I recently bought one as a test and it is a very good donor for a u87 clone, you can even use part of the switch pcb. I'm surprised no one analysed it yet. The circuit looks a lot like a u87ai in fact. However It uses a k30A as the main fet, while the dc circuit uses an A1015, a 2n5551 and a 2SA117. I didnt measure the voltages yet. It also has a transformer and the three 1G resistors that usually are lacking in cheap chineses microphones. I will post pictures soon

The BM600 has no option to change patterns. This one has. As the P420 has a similar circuit to the U87ai I would say my shot was not so far off yours. It looks a lot like the 420 circuit that itself looks a lot like the U87ai.

So i would say it is a good mic to mod or use as donor.
