Sad, poor quality Time Owned: 3 to 6 months.
I bought one to add to my station. Buttons to set clock stick. Not worth sending it back. Will not buy another. Sad MFJ usually makes good stuff.

Still going and going! Time Owned: more than 12 months.
My little double clock is still going after a couple of weeks now. Believe it or not both have the exact second to WWV synch. I guess MFJ must use different clocks now and made them better or something. All the other reviews looked bad here. Hopefully it will keep running good as it has been. 73 Jim. W5JJG

I'm gonna have to give it a 5 because mine works great.Both seperate clocks keep the exact time with each other. Small little unit but easy to see, looks good ontop of my radio also. MFJ makes some pretty good stuff now and then. Ok for me, no problems with this little unit so far. 73 Jim W5JJG

I did an easy little mod for mine.
Instead of using the #43 battery that came with the clock I replaced it with a #44 battery. The 44 battery is the same diameter but slightly taller. The back cover will not go on anymore. I just put a little tape on the back and slide it back in the holder. You can’t even tell at all. The 44 lasts longer. About 2 years. I have had this clock for 11 years a it keeps perfect time. I guess I got a good one or just had good luck.

Works as it should Time Owned: 3 to 6 months.
Bought this clock for the shack and to take while portable. Mine works as intended. I have taken it out into the field and use it in the shack. Easy to read and program, and has kept accurate time. I would by another.

Save your money! Time Owned: more than 12 months.
I've own this clock for about 10 years. I don't know why I haven't just thrown it in the trash. When it works it can't keep accurate time even over a few hours. And one quit about a year ago, even with new batteries. I and my club members have wasted money on several MFJ clocks over the years, and without exception none of them could keep time even for an hour or two. Buy a decent clock from anywhere, but don't buy anything MFJ. If you are that desperate, just send me your money. (Except for that little detail, how was your trip on the Titanic, Rose?)

not accurate Time Owned: 6 to 12 months.
Size is right, lcd display is right, if you are looking for a clock that keeps accurate time to WWV, this is not the clock. One runs several minutes fast, and one runs several minutes slow over a less than 3 month period. Accuracy is something this product will never be known for!

Very steady Time Owned: more than 12 months.
Yes the buttons on the side are crap... but I have had it for over a decade and just replaced one battery. Very easy to sync with WWV and it keeps accurate time. I only need to reset when we change to and from daylight savings (time to get rid of that anachronism!).

This is cheap enough and does the job.

I have had this for a couple of years. Worked perfectly, and not hard to sync to WWV. I am not trying to launch a moon shot; + or - a minute or two for my station logging is ok for my amateur needs.

This unit seems to have touched a nerve. MFJ seems to have a consistency problem ... I just may have been lucky.

It finally died after 15 years... Time Owned: more than 12 months.
Yes, I got my money's worth.

The buttons on the clocks are garbage. They take a lot of pressure from the pen one must jab into the switches' dimples to set the time.

I got tired of buying the correct expensive button cells and bought cards of different ones from Harbor Freight and at hamfests. I made this work for the last 5 years.

A new battery will normally last about a year. Both the local time 12 hour clock and the GMT 24 hour clock's batteries should be replaced at the same time.

This product is cheap enough if you want to live with or fight its quirks. I tired of doing that.

When the MFJ duo-clock finally died a couple of weeks ago, I tossed it and replaced it with a HomeMedics clock radio that had a 24 hour readout choice on its LCD.

I'm happier with that than fighting the old MFJ.

Plus my estate sale purchased HomeMedics radio also does babbling brook, t-storm, and other soothing sounds.

It also doesn't have the motor and moving parts of an old TyMeter drum clock that make grinding noises when they get old and tired (like me).

No problems, long time owner Time Owned: more than 12 months.
I've owned this clock for eons. It works okay.

There were several earlier comments that need some clarification...

Regarding setting time: you set the frequency, and then you can start the clock by pressing a button. No need to synchronize replacing both batteries at once!

Battery cost: any of these button batteries are outrageously priced at the local ACE. They are dirt cheap online, esp. on eBay. I've only needed to change batteries three or four times since I bought the clock, which I believe was back in the 90's. Also, the battery contacts must be clean and snug, that will cause fading display and other problems that may lead one to prematurely replace batteries. They should last for years.

Accuracy: they keep pretty good time, but I notice I have to check them every few months and reset as needed.

It is not a bad product, nor is it an exceptional product... but since mine has worked faithfully for 20 years I can't complain!

Pretty cheaply made - two separate clocks Time Owned: 0 to 3 months.
This is a pretty cheap setup. From the picture it looks like this is a clock with two time zones, and the selection of 12 or 24 hours display. What it really is, are two separate, non coordinates, plasticky clocks slid into a nice metal frame.

The frame is well built, but the clocks are utter crap. You can't get them to sync unless you put both batteries in at the exact same second. So you always have one click the next minute sooner. Not a huge deal, but just looks like crap when they don't match.

The "Sharp World Clock" on my Win 7 desktop is much nicer.
