I recently became active again and decided to try FT8. With the crappy winter weather, I was only able to get a random wire (approx. 71 ft.) in the air about 10 feet or so. Feeding it through a 9:1 unun to this tuner, I am able to tune all bands - even 160m!
The high bands work better and I have made lots of DX contacts on FT8 with it.

Good little auto antenna tuner
This ATU is fully automatic. I hooked it up to my radio and press the A/M button at the back for full auto tuning and that was it. Every time I changed to a new frequency and key up it will immediately do an auto tune and remember the tune settings. The tuning took about one or two seconds and you can hear the relays clicking inside the ATU. The LCD display shows the forward power, reflected power in numbers and percent and the SWR reading. It was able to tune my radio to 1.04 SWR. It can handle input of 100 watts, my radio does 60 watts but my amplifier does 300 watts so it won’t handle that much power and I returned the ATU not because it is no good but I need an ATU that can handle 300 watts. I highly recommend this ATU for anyone doing under 100 watts and save your headache trying to lengthen or shorten your antenna and changing coaxial cables to lower your SWR. In fact it tuned all 10m, 11m and 12m on the same antenna. My antenna is a vertical dipole using two 102” whips without the 4” springs.

This is probably one of the best antenna tuners for the price. It works on bands 160 - 6 meters, and the customer service was 100%.
If you can't find a 12V, 0.5A transformer plug to slice the DC plug to, you would be fine to replace it with another 2.1mm x 5.5mm DC plug. If you do, try to get one with 16-18 gauge wires, which will make it easier if you are hooking up to a power supply.
Overall, it works great!
