Think twice Time Owned: 0 to 3 months.
If it works, it works ok and it can tune a big spectrum of impedances, no problem there.
However, it only worked for a few days and then it failed for no particular reason.
I turned it OFF in the evening and the next morning it did not turned on.
No thunderstorms, no lightning or any other adverse weather conditions.
And there you are with your Chinese tuner, at the opposite side of the world…
After examination – it appeared that the fuse in the VCC line had blown. Also, the charging circuit of the internal Li Ion batteries was defective.
I contacted the seller and he agreed to send the unit back to China but I figured that was not a good solution as I was not too sure I would ever see my tuner again.
Ok, I know, that’s the risk when you buy Chinese stuff and I can only blame myself here.
I then contacted the designer Zhang Zhibin – BG3MZU. We agreed he would send me a new battery unit free of charge so I could repair the tuner myself.
Helpful, no doubt. Only…I never received the battery unit and he never replied on my emails again.
The tuner still seems to work on battery power and fortunately they do not need frequent charging.
As for the ease of use, I find the button combinations to perform all settings and actions quite complicated and difficult to memorize.
Also, if you bypass the tuner and you transmit, you get some kind of Christmas lighting of all the leds at the same time (including the power led).
Not really very assuring towards build quality and circuit design.
All in all, a bad choice.
Difficult to operate and poor reliability .
The problematic service is something you know upfront.
