MFJ Enterprises Original MFJ-260C Dummy Load, 300 Watt, 0-650 MHz, Dry

works fine

Perfectly meet my requirements.

Nice small load works great for my needs in my hobby in CB repair my radios

Its what I expected.

I measured it before first use. It was something like 40 Kohms, not 50 ohms. Inside, everything looked OK, but there was a high resistance connection between the clamp at the ground end of the cylindrical resistor element and chassis. I loosened that screw and wiggled the clamp around to make a better connection before re-tightening. Its worked fine ever since.

Works good for making adjustments on the radio without bothering others. Does what it says it will for low power under 300 watts!

This dummy load was DOA (dead on arrival). I tested with an ohmmeter and then with a Nano VNA, it was open circuit. I took the case off and inspected it, and did some probing with the ohm meter, the actual big fat resistor was 51.5 ohms, which was within the specification, that was not the issue. The problem is that one end of the resistor clamp relies on a push fit contact with the aluminum case for the return earth path. Aluminum oxidizes to produce aluminum oxide (AL2 O3) with is an isolator, so there is an insulator between the 50 resistor and the case. Ive read other reviews where people have fixed it, well aluminum can oxidize in as little as 1 month so I would not trust that fix. Im not going to risk my $1000 transceiver on this piece of junk. This is a very poor design, has a fatal error and can only be fixed by installing a dedicated copper earth return wire back to the connector. So I guess its true what I read online MFJ = Mighty Fine Junk

Small but important when you need to check your tuning. I have a 100W radio and this didnt get noticeably warm at all.

Great product value.

it works okay.
