When the price is too high to be true, trust your instincts. These are absolute junk. You don't even need a microscope to see it, the horrific editing is pretty easy to see. You get what you pay for and at this price I shouldn't be surprised. If you look at the prices from officially registered and reputable suppliers like e3d, you will see a very big jump in price and it's not fair. There are no production standards for them. Do yourself a favor and spend your money on good baits. If you want to get more bang for your buck, go for electroplated copper nozzles, they have higher wear resistance and better thermal properties, you can run at least 10kg of carbon fiber filament through them and still print without any problems. I would recommend doing some research on the reputable vendors available in the 3D printing community. Trianglelabs are the only clones I personally trust.
