I absolutely love this product!! I had read a lot of the user reviews for this as well as other blue tooth devices, and I purchased this device based on the reviews at this site. And it has completely met my expectations.It was fairly easy to set-up with my phone... but I did need to read the instructions. I usually prefer to skip reading the instructions and just do my own thing :-PIt is comfortable to wear, and fits my rather petite ears quite nicely. It is not snug, but it has never fallen off either.Voice and sound quality is great; no one knows when I switch from the blue tooth to the handset and vice-versa. Battery lasts for a decent while, though I have never talked for over 45 mins at any given time.The power button is hard to operate, and I have trained myself to power it on before wearing it and power it off after I'm done. It has made my hands-free experience failry nice... and I love talking through the blue-tooth while doing the dishes, folding laundry, driving... whatever ;-)
