## Customer Reviews

### ⭐⭐⭐⭐⭐ Awesome purchase
*by S***R on April 12, 2021*

Work well for connecting monitor lines on flat tow of my 2015 chevy spark to coach. Weather resistant. Be careful soldering. If you are not experienced at soldering find someone who is. Any plastic connector will melt if you get it too hot.HINT= tin the wire and leave it thick with solder. Put flux on connector terminal and gently and quickly tin. Heat the wire before connecting touch terminal with heated wire. Cool with wet cloth. Done. No melted connector.

### ⭐⭐⭐⭐⭐ So Far, So Good
*by D***S on August 10, 2022*

The product arrives as advertised. Though I have it installed, I have not powered it up yet. I have no reason to believe it will fail. I wish the manufacturer made a screw-terminal version of this product, though. Soldering this unit in place 20' up on a ladder on the side of a building is going to be difficult. Screw terminals would make my application simple.

### ⭐⭐⭐⭐ Pin/socket diameter
*by N***E on August 19, 2023*

The connector description states, “Soldering Pin Diameter : 3mm”. This equates to a #12AWG wire. There is no way possible the solder cups on these pins/sockets will accept anything larger than #18AWG wire (0.8mm), and even that is a tight fit. Since I didn’t expect the vendor’s info to be anything but optimistic, I was able to adapt to these small cups. While the connector backshell is long enough in the 6-pin version, it is barely adequate in the 12-pin. The connectors are otherwise excellent
