broken after the 2nd use

I did not expect much for the price. But, that the power supply is so hot after the second use, that a body melts on the side and a hole is formed there, I would have expected nciht. I'll check back later if I can adjust my photos defective power supply here.
I continue to use it despite the open gap on the side and have tried just always keep me as short as possible during use. Last time I needed a little more time and then it was finally broken.
You could hear then that inside what must have solved. Since it would be already broken, I made the power supply so on. Ultimately, it was just a part of what got anyway already glued a cooling plate (ie, the heat problem is well known), which I should have ranlöten again. I'm doing so much trouble me with the amount of money but not.
