At first I was over price and guarantee that it is an original part very pleased. After five months, the part but no longer works. Annoying thing is that I initially assumed it would be on the battery and bought me a new one. To my inquiries the seller so far not responded.
Conclusion: do not buy! ---- Addendum: Meanwhile the seller has again sent after the power supply has gone first allegedly lost in the mail. However, this "new" power supply is not working. For several weeks now I have no functioning power supply more.
