The delivery took place, although coming from Asia, after a few days. For the price you can not expect device, which is suitable for daily "craftsmen use" in the tool box. Nonetheless, it is surprisingly stable. My purpose is obtained by measuring its own batteries before charging and this is more than enough of. Measurable many battery variants: 9V (top), AAA, AA, A batteries and button cells (within the red slider). Another practical feature is the digital display, which I personally find better than the analogue display of other manufacturers.
