Very low loss on the low bands  Time owned: more than 12 months
I have had this tuner since 2009. It was worked very well for me. I have since upgraded it to a Palstar HF-Auto however I still use the 998 on the low bands. Due to the switched L design the tuner has very low loss on 80m and 160m. This can be confirmed by the QST tests which include loss in %. And since there are no air-gap capacitors there's no possibility of arcing which can occur on the HF-Auto. For the price I think the 998 is hard to beat.

Got it on sale from HRO Works better than expected.  Time owned: 0 to 3 months
I have had the unit for 3 months and find it works very well. Tunes my 160 & 80 OCFD's very well on bands designed for. Will not match the 80 meter OCFD on 160 meters. Opened the unit and found it to be well constructed and solder contacts very good, Quelling concerns about other MFJ product reviews. It won't let you load with more than 1500 watts, saving the equipment. Paint job could be better, but hey it WORKS as promised. The instruction could use a diagram to show where J1 is located, but it is clearly marked, once inside the unit.

Better than expected  Time owned: more than 12 months
After many years of running a manual roller inductor tuner I finally decided to get myself an automatic so I could move from band to band faster. I have had this 998 for just over a year now and it has worked fine from the day I took it out of the box. I found no loose parts inside and the soldering was first rate. The menu on this tuner is easy to adjust and set up and the amplifier keying line protection circuit is nice. The only things I don't like about it are the relays are a bit noisy when its tuning and sometimes it will fail to tune due to asking for more RF to find a match. Minor issues and only on certain bands with my doublet antenna. It does find a match on all bands and although a little finicky on 2 bands its my antenna system not the tuner. It has never overheated or failed on me. I have run an SB220 into it at full power numerous times on all the bands and it never gets warm. Combine this with a solid state amp and you have a sweet point and shoot combination for hunting DX.

Bigger display  Time owned: 6 to 12 months
What is with manufacturers and their insistence on having screens that require a microscope to read. A word to any manufacturer out there. If you insist on small screens at least leave an option to attach a larger monitor!

Other than the screen being ridiculously small and 10,000 submenus (just kidding of course but there are quite a few) the tuner seems to function fairly well.

I would have given the unit a 4 or 5 if it weren't for these 2 major downfalls.

Top notch and very capable autotuner at full power  Time owned: more than 12 months
I've had the 998 for about 5 years now and it has gotten heavy usage. At first, I located it outside at the base of end fed wires and verticals, protecting it in a plastic trunk. It worked very well as a remote tuner and I only used the metering and controls for setup and testing from time to time. Recently, I moved it indoors since I've placed a 4:1 UNUN at my 43 ft vertical. The unit works really well within the shack, including the connection to my IC 7600 for one button tuning. I like the metering facilities. It tunes better than the autotuner in my PW1. This is a fine product, but it is a piece of ham equipment requiring careful study of the manual and reasonable expectations about its performance. It does its job of tuning all bands well.

Old Reliable !  Time owned: 3 to 6 months
Upgraded to this MFJ-998 after having the LDG-600ProII give inconsistent results used with both a fan dipole and a 43 foot vertical. Sometimes the LDG matched, sometimes it wouldn't, mostly on 75 and especially 160. When I got this, I reset the tuner's memories when I powered it on for the first time, then ran it through the various bands and freqs that I usually used. Lots of chugging at first, as you'll have with ANY auto tuner when it's learning settings, then just a quick "burp" when returning to the same freqs a second time. Much to my delight, I've never had ANY problems on 160, and as you know, a 43 foot vertical doesn't present much of a match on 160 (or 75, for that matter). Bottom line, this has been a great auto tuner, has always been reliable and quick to tune, and the white backlit meter and green LED display look pretty nifty on the radio shelf. If you're new to auto tuners, remember that as good as LDG tuners can be, only MFJ has auto tuners that can work with any of the "big 3" manufacturers with only a change in cable. The other guys make you buy a different tuner for each radio, or simply won't work with Kenwood, unfortunately. Remember that ALL tuners work best if properly connected to a station common ground....YMMV... de KK8ZZ

Reliable Tuner  Time owned: more than 12 months
I have had this tuner for about 3 years. It has tuned all my antennas well. Most of my antennas are in the attic so I have a lot of compromises to deal with but this tuner still gives me a good match regardless of band.

This unit has made my operations a breeze, just push a button and voila!

I do run power occasionally and this unit can handle at least 1.2 KW. I do not have an Amp that runs 1.5 KW so I cannot attest to that experience. If you have an AMP the tune bypass is an awesome feature, when you tune it puts the AMP into bypass mode no tuning accidents with full power.

I find the meters to be pretty accurate and compares well against my analog meters.

I would buy one again with no hesitation.

Nice Tuner  Time owned: 6 to 12 months
I've had this tuner for about a year now. It has been totally trouble free on all bands from 80-10 on my 80 mtr. doublet. Tuning is very fast although a bit noisy. One minor gripe is the lack of peak reading capability on the meters. The watt meters both digital and cross needle are accurate right out of the box. Looking inside mine was very nicely made and there were no loose parts floating around or sloppy solder work. I also like the feature where it will shut off the keying line of your amp if your swr goes above safe limits.
This thing has me spoiled. After years of running a trusty SA2040 Heath which I also love....the fiddling with it each time I wanted to move around got old after years of doing it. I have this interfaced with my IC7000 so the button on the mic calls the tuner to do its thing. Very simple and works great. I don't even have to touch the tuner at all. I simply turn it on and off and do the rest with one button on the microphone. It even bypasses your amplifier without you needing to put it in standby when you tune.I have run near legal limit through it on all bands and it never smoked, arced or shut itself down. I run a short piece of coax to a 4:1 balun which feeds the doublet. So this tuner sees a wide variety of loads on all the bands and it never flinches. Its internal menu system is well laid out and very easy to navigate through. It just works. I think this is an excellent tuner for the money.

Works great  Time owned: more than 12 months

I have had mine for over five years and have never had a problem. It tunes 160 to 10 with no problem. I have done two or three firmware updates with no issues at all. I would recommend it to anyone.

Woouldn't take it to a dog fight  Time owned: 0 to 3 months
It needs a peak reading meter and it does not tuner correctly. I had it about two weeks and it started to have trouble tuning. Then it just stopped. The SWR detector went out with only 800 watts in. NEEDS HELP BUT could be a great tuner if they get the bugs out.
