Dangerous Junk			Time Owned: 0 to 3 months.
I had high hopes. Sorry. You can purchase the same exact digital panel meter, with a proper 50A shunt, but without the case and power poles, for about $16 on Amazon. As usual, MFJ continues to fascinate with dangerous misrepresentations. Immediately noticing that the amp reading was way off spec, I opened it up. Instead of a proper 50Amp precision shunt, there is a piece of 20 gauge or 18 gauge hookup wire soldered across the terminal that SHOULD hook up to a proper shunt. If someone really tried to feed 30 to 50 amps through this, they would likely have a fire. How can MFJ get away with selling this crap in a country where we have a Federal Trade Commission and Consumer Product Safety Commission? Lets check off the details: * Inaccurate, does not meet spec: Check * Dangerous if used at published current: Check * Poor design and implementation: Check But on the plus side, MFJ is consistent. Every one of their products that I have purchased failed to live up to intended use or design. Here are the one I unfortunately tried: * This meter, MFJ-4422. Junk. * MFJ-269c Ant Analyzer: Charging circuit that wont, knobs that break off, case that can not be put over the meter without removing knobs with set screws, rechargeable batteries that are defective upon purchase, a battery compartment where you need to remove screws to replace the rechargeable batteries. * MFJ-4230MVP Power Supply: failed 1 week after warranty, and MFJ invited me to jump in a lake, internal solder connections that looked like an angry 4 year old child built them, internal short circuit. * MFJ-264 Dummy Load: I'm the dummy for buying it. Try hooking it to a rig-expert Antenna Analyzer and doing an SWR sweep over it's specified range. * And finally, my friends A3s 3 element beam antenna: Multiple defective traps. Unlike the old A3s design, new traps do not use fiberglass, but use a non-reinforced internal plastic material with the consistency of licorise. And the trap coils are secured to the tubing with a sheet metal screw set into this self-lubricating soft plastic, so they loosen, causing intermittant contacts, and SWR swings. What is the summary here: MFJ is a code word for RUN. Run very very fast, in the opposite direction. MFJ seems to have taken cost cutting to the very boundary between dangerous and fraudulent. Rather than help people remain in the hobby at a reasonable cost, they really run the very real risk of driving many people out of Amateur Radio in frustration and disgust. Go elsewhere and buy some real products.
