This is a nice little charger, seems to be working ok.
As previously said , the instructions leave a lot to be desired. Needs to be in plain English and less confusing to understand.
Battery tester works well. Not sure if charging correctly though yet. Only used once and batteries did not seem to be fully charged even though the reader states they are, needed recharging quicker than expected.
Not sure if good value for money yet. Only used once but will update accordingly.
