I changed two controllers/transformers earlier for a friend. I was there to do six. I connected the first two and well, they blew up .

I’ve bought heaps of 240VAC rated items from AliExpress and not had a problem. They’re definitely cheaply made for the most part, and I generally give them a once over to identify any glaring issues… but I’ve got heaps of stuff out there working just fine.
Is it possible you got the wired mains to the low voltage side? I remember a box of LED drivers I bought came with the 240V side using red+black, and the low voltage side using brown+blue that looked awfully similar. Had one go pop before we busted it open and realised the version that came on the unit had the wiring colours the exact opposite. What made life even harder is that the top cover was symmetrical and had been put on back to front… so 240V was on the “correct” colour side.
