Goes, but ...

I use for a long time the battery tester of Aldi. Small, handy and pretty much even with good repeatability.
... And repeatability (repeatability) is most important to me in such devices: when the unit is something wrong, but always by the same amount, then I can correct the measured value slightly.

Now the new battery tester:

Negatives:
- Measuring accuracy: two digits after comma are unnecessary because devices have a tolerance of at least +/- 0.2 V
- No button for measuring. The measurement process begins as soon as the measured battery has contact with the tester. Since a good contact can not immediately ensure it always comes to repeated openings and closings of the tester what the life certainly not extended
- The red slider to the movable contact tilted slightly and can not be pushed so good

Neutral:
- Tester does not have a battery. Some consider that even as an advantage.
- Tester is pretty big, almost twice as large as that of Aldi
- Processing is acceptable ...

Positives:
- Repeatability is pretty good with my two testers - approximately +/- 0.1 V. This is acceptable for such a low cost tester for me. One constantly measures about 0.2V too little and the other constantly about 0.2V too much. I have appropriate sticker attached and can measure reasonable.

I bought two pieces and will keep both.
So, the bottom line is: no enthusiasm, but for the price acceptable => BUY recommendation for people who want the digital display at a low price.
