AFTER USING THIS FOR 3 MONTHS, I WOULD DOWNGRADE TO 1 STAR.I bought this unit thru Amazon, at a great bargain price with rebate, despite the warnings about the breakable ear clips. $5 net? What's to lose? Here's what's to lose: $5, plus whatever else you spend to keep buying replacement ear clips. (I've gone thru 6, despite treating the clips like I'm doing advanced surgery.) The unit works fine, pairs well, can be worn without discomfort and used for a long enough time, and it recharges well. The need to travel with a little charging case is not a problem -- even that works well. Yes its blue light blinks; and, yes, people look dopy wearing these things...BUT DO NOT IGNORE all of our warnings about the ear clip being brittle! You have to remove the clip every time you charge the unit, and not even Michael DeBakey could get it off and back on (essential to recharge it) consistently without breaking it. Mine broke even though I was painstakingly careful, so I bought several replacement clips -- now, that bargain doesn't seem so good any more. I'm down to my last replacement clip. I no longer recommend this unit. I'm off to find a resilient one, that doesn't suffer from this design/manufacturing defect.
