10 out of the 50 M3x8mm had non-3M thread. Impossible to mount a M3 screw.

Good value and I'm satisfied with these and will buy them again. But the finish on the "back-side" has scratches and it is somehow important for have a clean and even surface for optimal heat transfer. But I'll use thermal paste/tape to even it out so it's okay. But for high-performance-heat-transfer applications you might want to do some after-finish-improvement on these yourself.

The finish on these jacks are perfect. The "spinning-pressure-connector-brackets" (what to call?) are spinning freely as they should but do they provide good connection? I plugged them in a banana socket and got 0 ohm resistant. At 20v@1.5A the voltage drop was also zero, no problem. One could wish for a voltage drop test at 30 amps but that has to be another day ;-)

Rather bad finish, but it does work and will probably do the job just fine so I guess it's OK for the price.

I tested it against my Fluke 177 from 2.5v to 30v. It did a good job all the way.

I bought green and white. The LED has good enough light all the way down to 5 volt, even from any angle. Good build quality. It does take a rather small finger-tip to activate the switch, but I guess that's the whole idea with this kind of switch that you can activate is by mistake.

No description of terminals,B1, B2 and B3. No description on how to wire when charging the batteries. Haven't tried the board yet. Build quality seem good. See attach wiring diagram.....this helped a lot to understand :-)
