don't trust the star rating on amazon. the bad elf team is super responsive and the product is only months old on the market. the firmware is constantly being updated and as it stands right now is a super solid platform for pairing with an apple device.
i use this over the other options because i use the built in tracking feature while i'm out to save battery on my ipad / iphone. i only dump the tracks to my phone if i get lost and need to re-trace some steps.
