I was always taught that instruments should have 10x the bandwidht of the fastest signals that are being examined. Counters, generators, 'scopes, etc, though logic analyzers, due to their discrete sampling nature, could be used at only 2x. My LA samples at 2 GHz on its 500 MHz 'scope channels but a considerably lower rate, IIRC, on its logic channels.

The culture in the PRC seems to be that, once you have their money, you're never required to give it back, nor are you required to justify having lied/cheated to get it.

I use the "clip-leads" I bought from China to hold my napkin around my neck when I'm eating spaghetti, so as not to soil my clothing. I've found them, and many other, similar, products to be quite ineffective. If that's what they use in developing their hardware, I'm not convinced I should buy their products.
