Just what is your take on this review that I found online on this supply?
1.0 out of 5 starsThis item is definitely not UL listed and this is ... By Everett Schwartz on December 5, 2015 Verified Purchase This item is definitely not UL listed and this is dangerous false advertising. Just by looking at the wires used on this adapter you can tell it is cheaply made and probably not safe to leave plugged in for a long period of time. One of the rubber pads was missing exposing one of 4 screws holding the plastic case together. The text on the adapter claims UL listing but also contains a few typos such as "FORINDOOR SUE ONLY" and the mysterious text "Ne Pas uvvik avcun Aucun elemnl reparable" which is no language that I or google recognizes. There is no way I am plugging this adapter into my wall.

As I said when I pretty much started this thread, I got a bunch of
power supplies that were put in when my kitchen was redone and they
were noise bombs on 40m (my lot is 42x100, and I'm running a D-140
abot 30 ft straigt up from the supplies. That said, you can hear them
on the Tecsun 660 from a few hundred feet away with the antenna folded
on "local" attenuator setting
I JUST got in a supply via Amazon - also a 12v 5A supply, that was
advertised as UL Listed and EMI Free (right in the description). It
is marginally larger (about 3/16 longer, and about 1/8th wider and
thicker)
Even with the Tecsun right NEXT to the unit on local, I can't hear it
on or off!!
The BAD one is labeled:
Model GHD-1205N60S
and shows UL Listing and CSA, C E, TUV and a bunch of other markings
The NEW one is

For ME, it WORKS, to the point I just ordered another 4, to replace
the other bad one in the kitchen, and do some other lighting
