Query: Best thing I ever got for my cell phone!

I bought this at Amazon after seeing it at other places for $70+. I was able to connect it up to my Nokia 6230 in literally 30 seconds after reading the easy instructions. Good sound quality, VERY LONG battery life.I'm a techie and I have never found anything which was so easy to set up and get working to a more than satisfactory level. Truly plug & play!
