This is a great idea but implemented very badly for me. I was willing to pay extra for the convenience of having battery replaced at my office. But, after fighting with a non-responsive website to schedule online, then an equally non-responsive chat I finally called. Made an appt. Aftert the time I was promised passed I called and was told the battery I needed wasn't available until the next day at a time when I couldn't be available. When were they going to tell me this. A lot of time wasted for what was supposed to be a convenience. I cancelled and will take less time to get my batter for probably 25% less. Ugh!
