I bought this from Amazon a couple of months ago and I couldn't be happier with the product. I am using it with a Treo 650 and I had it working in a minute (literally).I admit I'm not a constant wearer - I only want it for when I am in my car commuting and the local law does not allow cell phone use without a headset. As such, I turn it off and store it in my car when I'm not using it. One charge lasts a very long time.This headset isn't feature-rich, so if you're an all-day wearer, this might not be it. However my main considerations were simple ease of use, low cost, reliability, and great sound quality. It meets every critera. The only gripe I have is how keeping Bluetooth on drains my Treo battery, but that's not the fault of the headset.
