Yeah, I'm keeping the ones he sent. He hadn't asked for them and I'll tell him to blow it out his rear-end. I'm still holding his feedback over his head. Told him to get me the right product and I'll look past this crap. Least I can do, for 2 free ones.
Quick update on this one. It its tiny. Smaller than most adult palms. I set it up, turned it to my mark and fine tuned with multimeter. Set it, as close to 12.00 as I could get it. The crap digital display vvps I have, is impossible to set to a solid voltage. It will drop significantly from what you initially set, by up to several tenths of a volt. It also gets hot as Hell, without a fan blowing on it, the entire time its on.
This little thing hits the voltage you want and as long as you don't bump the dial hard enough... it only varies hundredths of a volt. I set it at 12.02V and over the course of my session, which included unplugging it from the HI several times to check voltage, unplugging and plugging it back in, removal of power switch bypass for drain measurements. Every time I got it hooked back up. The voltage did not vary by more than .03 hundredths. It was just resting on some laundry to. No cooling fan and it barely got warm.
I hate to say it, but if the voltage readings/marks stay consistent... this little thing kicks ass.
The bad news? The other one I got with this one. If I set it even close to 12V on the dial, it reads significantly higher on a meter. Over 13 volts.
