Pretty good little unit if you don't use it too much. Nowhere near the claimed 3 hour battery life. If you have a cell phone you use less than 1000 minutes a month, this might be the one for you. If you use your phone for business like I do, over 3000 minutes a month, then DO NOT BUY THIS UNIT. I am a lifelong Plantronics customer and I cannot recommend this unit for business use.
