Ordered the Blackberry battery in the morning and received it in the afternoon the next day. Very impressed with this service. It came with a tool kit to aid with installation but with no instructions. After much frustration in trying to determine how to install it, I took the new battery and my Blackberry to a Cell Phone repair centre and had them install it for $$67. The Cell Phone repair centre did say it was quite difficult to install. Therefore, I can only give them 5 stars on the ordering and delivery but not for the overall experience.
