My ultimate goal was to get a very light weight battery and the braille is light (and compact). I haven't had it long enough to comment on longevity but from what I've read...it should be at least average. View more reviews...

Bought this for my daughter's car at college since she does not drive it regularly. The Bluetooth connection lets her check when she gets in the car if she needs to charge the battery to use it before a trip. Very useful. It does hold a charge for several months and the app guides you through the connection process. View more reviews...
