Firstly ,
1. battery lasts up to four hours
2. comes complete with sd card
3. small / compact
4. aluminium case (not plastic)
5. excellent picture.
all very good selling points , i had the cheaper action cam by comparison this is a decade ahead in so many ways.
I cycle with mine it lasts the whole ride and gives perfect pictures (apart from the shaking)it looks like another torch attached to the bike so i dont have any issues with strange looks from passers by.
it does have some down sides by comparison to the earlier model, the charger system (by usb from laptop)could be so much easier and better with a seperate charger for direct current or cigarette lighter, once the powers gone its back home to the pc and recharge.the on/off switch is below the cap at the end , i don,t see why it could not be externally mounted on the case, if it rains its a case of unscrewing the cap exposing the inside if you need to turn off. the bracket that is shown on the listing is not the bracket that comes with the camara, its far far far cheaper with rubber bits to hold the camara in position, i cannot help but wonder if the bracket shown would do a better job of keeping the camara still whilst riding.
Still all that said I can still see why this is worth the £43.00 I paid, i would recommend to anyone even if its for peace of mind most cyclists will tell you of their close shaves with car drivers , at least this camara will record them and should the worst happen .....be availble in good quality evidence.
