So i do not like that the SW30 does not have the Possibility to sound alarm When the cellphone gets "out of reach".
And, but this is with all of These gadgets, When you drive your car you have to shut down for a few secondhand te watch Because otherwise the Bluetooth from the car can not connect to your phone (Bluetooth can only connect with one string at the time, so answer mode can not be connected at Both at the sametime) but this is not the SW30 his fault.
The speak and listen function of the SW30 is fantastic and my biggest reason to buy this, now I do not have to jump to answer my phone..great.
