I just purchased a set of 5S units.... one for my helmet and one for my girlfriends...    Not very impressed for what you have to pay for these to be honest.    Biggest complaint however is the static between the two,  We were riding together (her with me on my bike)....  she could not hardly hear me because of the static in her unit.  This is unacceptable in my opinion.   Just purchased these brand new 2 days ago (10/1/22) at Cycle Gear in Bedford,TX.
