It took me just a little time to get used to this headset but I do love it. I have to admit that for the price, it works really well. Sometimes, it loses connection even though the power is on and bluetooth is blinking blue light, but if you reset it, it reconnects. Sometimes, I have not heard calls come in so reliability for me has been around 95%. I am giving it 4 stars because for the price and comfort, it works quite well. Watch out for battery drainage on the cell so if not using, make sure to power off the bluetooth Power On to Off. It is a concern not to lose it - it's small and without wires. I left it in the Juice store but it was right there when I went back (lucky me)!
