The other day I used it and it worked great, then the next morning it was total static and popping in the left ear speaker. Came individually bagged to get the shoes form. Our little big Cosmos wears pjs for about 3 weeks and then moves on because they get too short for him. And the initial setup wasnt actually bad at all. Here we are in the month of July, and all 12 units I received have an expiration date of 10/2020. These are cute they make me smile. Like the swivel so fits in either ear. My Zolos had a light that flashed every few seconds but it was barely noticeable; these Panasonics light up an entire room, I’m not joking. Not really for even slightly wider than normal feet. I have one hard kayak and 2 inflatables.
