I beat 80% of all thing surrounding you came from China, including your chairs, dishes, carpet windows, Ipdas, phones, ligths, car parts with few exceptions.
Well, I don't have an iPad, but yes, there's a lot of Chinese produce. Almost all of which is produced to specification and supplied by a more local company, or at the least one more versed in dealing with the western world, so I don't have to filter the garbage. Unlike random online sellers, they're held to quality and safety standards.
The windows fitted more recently are manufactured in the UK, though. The glass was made 10 minutes down the road from me.
The point to pay more to get a quick component locally is totally valid, But pointed the finger that everything in China is fake or not tested or bad quality or gray market isn't true, Have parts for all flavors from a simple Atmega fake Arduino to a developed and made in China Infrared grid array to be used on missiles. Don't label China as grays market, There you can get full spectrum, you get what you paid for.
I'm not labeling China as a grey market, just the companies (which is often a generous term) who do small-scale business with the western world. Buying parts off Aliexpress is an extremely dodgy game, especially when it comes to parts no longer manufactured, triply so for parts never available in small quantity to begin with. And the trouble is, you don't
know what you paid for, because pricing over there is so utterly alien, and what we'd consider lying is standard practice.
Now, if there's a legitimate, reasonably well known company in China manufacturing LM3915s, whether it be a direct die copy or a functional equivalent (without copy and pasted specs and graphs), I'm all ears. It'd be great to hear someone is producing them. But, like other famous chips before it (XR-2206 springs to mind), I sincerely doubt anyone is - they're selling old stock if you're lucky, salvaged parts if you're not too unlucky, and outright fakes.
