sabrehagen, thanks for your kind words about me, but I'm afraid I have to disagree with your rosy interpretation of the reason for, and implications of, the bad English on your remote control receiver (and other cheap Chinese products).
The very poor English on the label of your receiver is actually a sign that the manufacturer either doesn't know that his English is beyond being understood, or can't be bothered or can't afford to have it professionally translated. In any case it is a clue that the people responsible for the product are unprofessional and irresponsible. I think in those circumstances, the question "what other shortcuts have they taken, and what other quality and international safety standards are they unaware of?" is a fair one to ask.
In this case, the receiver only uses 12VDC so there isn't an immediate safety issue there. But your $3 mains power supply is something I would be concerned about. As an example let me tell you about a laptop power supply I bought recently. It was a no-name Chinese product imported locally and sold for NZD 36 which is VERY cheap for a 120W switching supply. The mains cable that was supplied with it wasn't properly wired, and shorted out with a bang when I moved it. The importer replaced it, but even the replacement one would fail a basic safety test. After a few bends, the outer insulation (which is quite stiff) simply broke at the join with the connector, then the inner insulation started to break apart too, creating an immediate shock and fire risk. The reason is simply that the insulation on the cable is too inflexible. This type of budget-related shortcut is common among cheap Chinese-made products. The power supply itself gets much hotter than it should. I will try it in my application. I don't know whether it will be usable or not.
I want to make it clear that I have no dislike for Chinese people, and I'm also aware that China is capable of making very good-quality products when the people and companies involved are held to high standards and properly funded. I have owned several Palm Treo smartphones that were made in China and were of very good quality. I believe Apple get their hardware made in China. My criticism is of products designed by amateurs to an extremely tight budget with little regard for quality, reliability and safety. The attitude of these people seems to be that if the product LOOKS like something good, and at least SEEMS to work, then it's alright to sell it.
Here in New Zealand we have a lot of "two dollar shops" where low-budget Chinese products are sold. My own experience is that electronic devices bought from these shops sometimes don't work right out of the box, and if they do, they usually fail within a short time. They are usually made with obvious weaknesses and failure points. They are clearly made with little or no regard for quality or safety.
We also have a chain of shops called The Warehouse, which also sells a lot of Chinese-made products. They are regularly on the news because of safety failings in products like children's bicycles, toys and prams. Many of their other Chinese-made products fail just as badly, and are made to equally poor quality and safety standards, but don't get on the news because they aren't an immediate danger to children. Cheap Chinese-made products generally have a very poor quality and safety record here. Some use obsolete components and chemicals that are banned. For example I bought a portable vacuum cleaner that worked for a month or so, and contained Ni-Cd (Nickel-Cadmium) rechargeable batteries, despite the fact that these had been banned for years because of the danger of Cadmium in the waste stream.
It's nice to imagine lots of responsible hard-working people in China just trying to get ahead, and that may be true, but from our point of view, as the recipients of the cheapest possible Chinese products, which are designed and manufactured with no sense of pride or responsibility, we don't see it.
