Nice vid, does this work with an older alpine (not factory) car radio, and why don't you have it in stock? Thanks

Will it be wide enough for a HTC One M8 with an otterbox commuter case?

[MrAnt]

Is the audio quality comparable to CD?

[TonyHammer]

So I cannot listen to an FM channel other than a blank one in order to have hands-free calling? What is the point of that?

hi, could you please tell me if it's compatible with the Sony Experia Z Ultra.... thanks a ton..

I bought this for use with my Samsung Galaxy Ace Style phone, it shows on the compatibility list but it does not transmit to my stereo.  I see my music on my phone playing when I push the play button on the transmitter but I have no sound going to the radio from it.  Any ideas on what might be causing this to not work properly?

It doesnt sit firmly in the lighter hole.The phone is heavy and the fitting os loose.On the move it shakes and keeping focussed on.moving screen isnt the best thing.IMHO

shame this one is out of stock everywhere!

i'm glad to see how many times the thing felled out of the cigarette lighter plug..smh ..definitely not good for big phones
