I bought this headset for use in my car during my &lt; 20 min. daily commute. So, keep in mind that I'm not a power user nor do I have very strict requirements for it. I've used this headset for a total of a few hours (had it about 1 month) with a Motorola Razr (the first version).Bottom line: It works great! It paired easily with my phone and all the controls work as you would expect. I've only left it on standby for a few hours, but it worked fine. The volume and call control buttons work easily. Other reviews note that it is hard to turn on while wearing. I haven't tried this, but I could see how it would be true. You'd have to hold down the power button, which requires significant pressure and would be behind your ear. For my use this doesn't matter: I turn it on and put it on my ear when I get in my car and do the reverse when I get out.I would definitely buy another (already bought another as a gift). I think it is a great little headset, especially for the price (~ $45).
