Unfortunately, I realized that the functions after about 2 weeks was no longer present. I then had again expanded the battery and charged separately, but found my charger that the battery was already broken. OK, I took out a new battery, but also with the new battery could no longer be brought to life the mole fright. For the money, you can certainly do not expect much, but I've assumed that the operation lasts longer. Due to the low cost compared to returning so I abgehagt the topic under "losses". Maybe I had just caught a Monday product!
