I bought the WORST fairy lights on eBay (so far)

The fact the listing starts with the word "economic" turned out to be a good sign, and I hadn't even got around to starting the video before I inadvertently crushed the 240V enclosure between two fingers while pondering how flimsy it felt.

Beyond that, the smoking hot resistors - complete with hot plastic smell, and the minimalist control PCB show the true pedigree of the product. Sometimes I wonder how many electrical accidents they have in China, where this product is probably common.

They could have made this marginally better by using a resistor in each light and reducing the current to a level where they didn't dramatically exceed their rating (about 0.125W). This is where a lower supply voltage like 120V has a huge advantage, as much less power has to be dissipated in the resistors.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm
This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
