Finally, no more throwing away unnecessary battery

Is I hardly think one type batteries (rechargeable batteries), which can not be inserted.
He is due to its convenient size, always handy in a drawer
and the display division is again quite detailed, as well
or bad battery is.

If then, for example, a device like my Logitech Harmony with fairly high
Battery needs no longer enough by "flagging" battery
Gets power, is easily measured once briefly.

If the display then confirms that the battery only one-third
has its power, this comes up, for example in alarm clock or some other device
with little energy needs to the end used.
I mean, the tester helps saving.

Am absolutely satisfied.

Strong buy recommendation.
