This is not a new thing though is it? Back in the days of the USSR we used
to get a lot of stuff like cassette machines and radios and even black and
whit tvs from Soviet bloc countries. Some were OK, but a little fragile but
one I remember made by a company in the Czech area called Tesla had a
great design and a great sound as a recorder player that ran form the mains.
The sad part was that it seemed to have been manufactured by idiots in that
all the riveted bits were loose, the flywheel was not on straight and the
motor and induction type, was doubling as the mains transformer and
basically over a three month period it gradually fell to bits chewed tape
and finally the brackets that held the piano keys fell of completely.

Like most things, a lot of things are designed well but cheap manufacture
and lack of quality control and corner cutting on components ruin them.

An LED striplight. After 1 month, BANG! A puff of smoke and a hole blown
in the side of it. What I think used to be an inductor has exploded with
enough force to rupture the casing. Funny thing is, it continued to work
for a day, and now works if I tap it.

I no longer trust anything Chinese that has to have power running
through it. I ordered six so-called "20 amp" 12-24 VDC LED dimmers a
month ago. Out of the two I tried, one burned up within minutes at only
5 amps at 12VDC, and the other burned after several days running the
same. The latter actually went without warning, but at least the first
one was running hot so I actually didn't leave the area for fear it was
going to burn. Good thing I have a strong fan to evacuate the fumes,
which would surely be toxic in short order!

None of this Chinese crap is UL listed and thus just about anything can
happen. The ONLY thing I might take a chance on are older ATX power
supplies. At least those have a listing and, although still not UL, it
is better than nothing plus US PC manufacturers don't want to be sued
for their computer burning down a house.
