Phono Cartridge Purchase from Asia?

If you buy "grey market" goods from overseas they will not be covered by a US warranty and the sellers generally don't accept credit cards, so yes, there's a risk.  Know that going into the purchase and decide for yourself if it's a good deal or not.  I bought a cartridge from Kron and wouldn't hesitate to do it again.

There is a downside. No warranty. I broke the stylus right off one of these cartridges. (The Benz). The manufacturer denied the warranty claim. I sent it to a third path repair facility and all is good.

It's unlikely that user damage / misuse would be covered under any warranty.
