New head takes new Epi ;-)

I bought on the basis of the article reviews; some have the same problem explains the purpose battery.
In my case a fully charged state has only 5-10 min. Persevered, then already the red light, the battery has shone the breaks down.
Behold after the change he has. By loosely held 1 hour again.
Have seen a few months and unfortunately I have been for a short time a minimal deterioration already regard the stamina (currently 45 min.) With a fully charged state it now.
Despite everything, I am very excited because I have so saved me a new Epi.
