You cannot buy better for the price. The unit came in 9 days after the order. Looks very good and works very good too. The only thing is a poor 220v/120v adaptor for the ac cord. the pins are too thin and the cord falls off the wall plug all the time. But a regular ac cord can be used and all is ok. Overall I am more than happy.

J'ai acheté une quarantaine de ces connecteurs parce qu'ils me semblaient parfaits pour l'utilité que j'en fait. Cependant je me suis vite aperçu que les petits leviers orange brisent très facilement. J'espérait fabriquer des modules de test pour mes élèves en domotique mais ces connecteurs sont beaucoup trop fragiles.

Good webcam, sound is loud enough but a little muffled. Very hard to focus, the focus wheel is very hard to turn. Win 7 and 10 found the driver instantly, and the little stand is very useful, you can put this camera almost anywhere and the stand will fit. It can focus as close as 5mm.

Upon reception, you must check all parts on the board and make sure they are not touching together making a short circuit. This happens in transport. After that, it is a good idea to resolder the power transistor, transformer and other parts badly soldered. Once this is done you can power it up. Check the polarity of the output with a voltmeter, do not take the little + signs for granted. This SMPS monitors the 5 volt line witch means the 5 volts is always good but the 12 volts will vary depending on its load. Overall, you get more than what you pay for.

Not dark enough when MIG welding. There is a large spot in the center of the lens (about 50% of the surface) brighter than the rest. There are comfortable to wear and the flip lens is useful.

Amazing little tool, works exactly as described. Strip and twist. Works better on a drill than with the hand.

Q: where do we put the + and the - in input ?(I know where the input is but don't know how to differentiate the + and - on the card)

Asked by gabrielgerbouin on 2019-04-15 07:25:42

Francois Robitaille The input is AC. So normally, either way is ok. Should you decide to input DC, the diode bridge in the circuit will take care of the polarity. So do not worry about the polarity at the INPUT.

Got it very fast, very easy to program as the instructions are, for once, clear and precise. It works as described but it is not very accurate. Overall, you get a lot more than what you pay for. I'm happy with it.
