Very good surpasses my expectations in view of its low price. I recharge my cell now only 2 times per week maximum wide (roughly every 4 days). Of course it all depends on the use of each but in any case for me that was the old battery recharge up to 2 times a day in recent weeks, I am delighted! J have the impression of having a new phone! And very fast delivery (4 or 5 days of memory) I recommend this product and seller!
