Controlling the addiction is tough, and $11 is not too much to play this lottery. The prize is questionable though.

Btw, small display with red numbers that you see, says "Work Mode", not "Volts", and 16 is kind of unusual for a battery voltage.

Almot, get over it! We don't all need fancy Rogue controllers.

My little 20a controller I just got for $13 from Hong Kong via ebay works great. It is not a dubious item. I reported on its performance recently in RJ's "Oh no" thread.

And for newbies, it is a lot less expensive when you make a mistake in the wiring or procedure or go over the Voc rating and fry your new controller (which you can do with a $400 controller in the blink of an eye too) when it costs $13 to get a new one and try again.

In fact, you might as well get two in the first place, it is so easy to make a mistake and fry a controller. (Don't ask me how I know that!) In the same category as frying the 10a part of your multimeter switching back and forth between amps and volts--you will fry it eventually. On that, I finally got a better one that has a 10a fuse you can replace. :)

IAW it is more likely IMO that you will fry your controller by mistake than it will fail due to being poorly built.
