These are much cheaper than other gold plated adapters, but every other adapter has a polished look to it (like the picture here). The actual finish of these is almost like spray paint--it's a matte finish that's not smooth.
Functionally they work well (as would even non-gold plated), but the gold is for corrosion resistance which I hope these can do. They're going into an environment where there are moisture and temperature extremes.
I have a four camera system run to 110' away from the central system. My system came with 60' cables, so I bought four more 50' cables and these connectors. I got everything run and the resolution on all the cameras is great. These connectors were a great price and made my job much easier.
PROS: Great price. Quick Delivery. Full resolution and compatibility.
CONS: I wish I would have ordered them with the cables to save on shipping. All on me.
