Utter rubbish

The first two months, the device worked flawlessly without load showed the Vebrauchsanzeige 0.0 watts, and the gemessenenen values ​​of various consumers (I measure primarily equipment with low Leistungsaufhahme) also seemed to be correct.

After 2 months I noticed that suddenly permanent 1.0 Watt was displayed without load. A review of the batteries fallow nothing enlightening, also repeatedly removing the batteries and press the reset button is also brought no change.
Well, I thought if it remains at the 1.0 Kostant watts, I can just still so life. But far from it, other weeks the value was always lower, until he again reached for a short time, the 0.0. However, my confidence in the device's breits dropped to zero at this point, a consideration of the values ​​I have only performed sporadically, until I noticed that the display always been difficult to read what lies close to weak batteries. So I have got new batteries worried and hoped that the problems would dissolve so in air, but this was not so.
With new batteries the display was indeed again perfectly legible, but the unit will show from now on nothing at all, only 0.0 in all areas (voltage, current, power).
Now, however, "special tools" and on dug out with that thing. Everything looked good, except for some solder joints that looked as one who had never seen a soldering iron in his hand had (creepy horror)
After some time of around tasting (do not worry, I know because of, but still not recommended for imitation) I came to the conclusion that the input capacitor (275V 0,33μF) must have .a Macke. So could an already half-schlachtetes PC power supply act as a spare parts store and have a switched capacitor vegleichbaren from parallel and lo and behold, it comes back.

Conclusion:
That a capacitor after such a short time gives up the ghost, simply must not happen, because really substandard components were apparently used. The faulty 0-load indication is unacceptable for me that may not be easy.
So my advice, stay away from this unit, it is in my view simply garbage, I would buy it under any circumstances again
