Phono Cartridge Purchase from Asia?

@lloydc thats a good question. I can’t seem to figure how to identify the seller either 

The seller is Kron, I purchased a Benz MicroSL from him last year the sale and communication were smooth and perfect.

This seller has many hundreds of sales, go for it.

Seller may be 100%, yet clearly crossing distributor lines and such. Does seller offer warranty service?

I’ve personally purchased a few cartridges from Kron, and yes he’s excellent; the Benzes are legit and have always been perfect.

I have yet to require warranty service on any cartridge (most cartridges will either die by accident/abuse or by worn stylus after many hours), and at the cost savings you can buy another new and still be under the normal price anyways.

I bought a Ruby Z from Kron. Fast shippin and responsive. However, the serial# was changed on the outer white paper that wraps the case. I reached out to Benz. Apparently, my carts serial # doesn't exist to them. They called it a grey market cartridge. No warranty will be honored as far as they're concerned. The cartridge seems fine but what did I buy; who knows? I wouldn't do it again.
