I can not tell the difference to my original in battery performance.
Also on this page all positive!
I would like to highlight the efficient and friendly customer service!
On my charger went after a short time on a small defect, whereupon I sent an email to Bundle Star.
Within a few minutes was very friendly responded by agreeing that compensation is virtually on the way to me.
Two days later I received already the package. I did not need to return the old part also.
All in all very satisfied!
