its not just silly, its going to be inconsistent, they have no standards to adhere to other then looks good and is non toxic for nail polish, who knows when the sales director in the company feels like letting a bad shipment through that does not stick so well for a fashion company (oh they change the nail color every day now according to new marketing data, who cares if we make it a little weaker in the summer months when consumers are dating more). People make money by making inconsistent products and carefully managing supply lines based on distribution region, unlike professional/semi professional products. (that disclaimer about using product outside of use makes them money).
" I know, we made a crappy batch, but you know I talk to the people in the xyz fashion store chain in the xyz region, they have consistant customers, we can get rid of it there safely).... we don't expect the backlash to be that bad there " (so long they think they can make money and not risk reputation too much). Also, a good reason why to buy from a distributor if you are running a business, rather then buying direct from another company, because their sales guy might 'get to know you'.
(this is why some people don't like giving company tours to sub assembly vendors). Then at least, you are protected by the whole distribution region.. sorry to hear if you are in a poorer country. One example is European potato chips (poorer countries get worse quality chips like Lays.. expect fragmentation when you open a bag in eastern Europe.. (no, its not shipping problems
lol, its practically racism). Brand name is not a brand name with these guys.
Supplier asking you too many questions about something non suspicious? Its a sign they are binning their products.
IMO dangerous because someone might get the idea that your measurements will be enforced by the company and it could lead to failures. Well dangerous in the sense that you might end up with a bunch of bullshit that has problems down the road, and for cheap companies. At least structural glue has to not fall apart, so its safer for consumers.. but cosmetics......
i don't know if there will ever be a reliable industry watchdog for nail polish RF impedance. this is why i don't like it being used for trimmers, because someone on a assembly line doing something important might think they can get away with it.
Another example of misusing parts for electronics: I decided to make a bus bar to hold an electrode by filling a copper pipe with solder. I put what seemed like too much solder into the thing to fill it, while it was carefully heated by a torch after the pipe was cleaned. I look on the floor and there is drippings of solder. And it turned out the side of the pipe disintegrated and was leaking solder (careful to all the crazy people using plumbing for water cooled induction heater coils, I had a hunch it was a bad idea and this was for a 6VAC application). I cut it carefully and did nothing wrong to the pipe, fluxed it with proper flux, etc.. (everything correct, gentle flame). Looked perfectly fine during visual inspection.
