anyone found these things to be any good?

I blew one up within 5 minutes of toying with it, I think I saw 7 amps on the display for a short time though (I was running it from 30 volts)
the board has three leds. one for voltage in, the other two for voltage and current mode. current mode is blue iirc.

the pots are 30 turn pots.
The display is auto ranging, 0.00 to 99.9 volts, I didn't run it that high though. The brass standoffs are live, so you don't need to use the connectors on the panel board.
Current is set up for an inline ground referenced nominal 50 mOhm shunt, which I actually measured to be 53mOhms on the main board, and the panel meter will read 0.00 to 9.99 amps.
I don't know if it will auto range over to xx.x amps but 10 amps through 50mOhms is 5 watts anyways.
The LED display isn't very readable, they are over driven and a single layer of silver esd bag material cuts the glare down fairly well and makes it readable.
