The waterproof bit was slightly misleading

On the downside, the price does seem a bit steep--but I figure I'm partially paying for the name "GoPro".

Less than average battery life, a bit disappointed with this

The only drawback is that it does seem to drain the battery a bit faster since the two devices are constantly connected, but they were generally able to have it last most of their rides during the day.

A little bit bulky for its function.

also it won,t even charge anymore after i charged it the first time
