I was anxious about buying a battery sight unseen.  I chose this battery based on its matching the dead one & customer feedback for BTO. I placed the order late on a Friday night; it was in my mailbox Thursday morning. The product arrived the first day of estimated arrival; so relieved!  Easy installation; took around an hour to charge the battery initially, and I've got my phone back and all the power I need! So happy I don't have to replace the entire phone.  I highly recommend this product!
