2.0 out of 5 stars Interferes with laptop wireless connection 3 Aug 2013

This product works well, it is flimsy as others have noted (I broke one and had it replaced and i'm now very gentle with it)
I bought it to stream music from my laptop to my stereo system speakers which it does well but unfortunately the wireless transmitter breaks the signal for the wireless internet so I can't get online while i'm using it which renders it virtually useless.
If there was some way around this i'd be very happy with it....
