Got it in two days and it did the trick perfectly.
Great product at a reasonable price. Used it to replace the cold-start relay for the glow plugs in my jeep. OEM are not available any more and this worked perfectly. Thank you!

Had to order twice
Had to order another one of these as the first one that was delivered was missing the relay. First one only had the connectors. Second one arrived on time and all parts in this one. All as described and easy to fit.

Works perfectly
Great quality relay with big bolt on terminals. It works perfectly and gives a satisfying clunk when switched on and off. I use it to switch a large amount of 12v halogen and LED lighting and it hasn't missed a beat.
