1000M Handsfree Bluetooth Intercom Set for Motorcycle and Skiing Helmet (7-Hour Talk)

Pros: Small and slim.
button are big, glove friendly.
volume is loud.
Has FM radio so won't be bore even if your phone ran of out songs to play.
light and ease in mount to any helmet

Cons: so by, my set can only last 1 day or less and i only use it when i travel to work and back. occasional calls etc. nothing heavy but the battery life can't last me till end of 2nd day. wonder why. maybe my set is faulty?
FM radio station does not sticks, so when u off your set, and switch it on again. you need to re-scan the stations.
no voice dail button, so Iphone 4S users, u can't use Siri with this.
no skip song buttons as well.
Voice call as review my by friend, background sometime is as quiet as u are in the room but sometime is very noisy.. wonder with the noise cancelling work.

Other: out of the available BT interphone available now, this is yet the smaller and slimmest of all.
but for the price and the defect i used so far, it is an expansive item as function does not work well as it seems and the (my) battery life is bad.
