Rotscher Neuweiler
expected and almost fulfilled Quality

Perfect. Small, Quick, ultra connectable and easy to use and to carry along. It works perfect and the app overview ist also super. There is only one negative point to mention: please integrate also the possibilities to discharge, analyze and rejuvenate old batteries. As a suggestion please integrate also an overview to show the condition of the batterie. Not everyone is capable to understand resistant digits.

Thomas Mühlhausen

With app so much could be done, akku Database etc. - but nothing implemented
+Firmware update is comfortable
