WEAK, BARELY CHARGES BACK UP,  battery---DO NOT BUY
battery "BARELY" CHARGES BACK UP AFTER 1ST FULL CHARGE...THEREFORE THE SHAVER IS  extremely slow and weak. I recommend you don't waste your money on this. when I emailed their technical support about this issue... they "ignored" my email and did not reply. so "warranty" is FAKE.
