It's been about 6-months and I have already went thru 3-of-these already. The first I received - like a # of the other reviews - came, however the mic did not want to retract. I could not turned it off. I notified the seller and another one was sent to me. This one too had the same fault. The mic did not want to retract so I could not turn it off. I then asked for a refund. I figured I'd take another shot and order yet another one thru a different seller. This one worked fine for 3-4 months, but the same fault occured not long after. The mic would not want to retract. After giving up, I finally took apart the unit and the fault is with the assembly. Living in Hawaii, I assume that living in hot, humid areas results in these faults. I now found that the mic does not work now and found the lead has broken off. So either take the unit out of the vehicle when not in use or be prepared to have trouble with the unit. My friend in Seattle has had his over a year now and has not had any trouble....
