I bought one of these as my first hands-free and absolutely loved it. Unfortunately it stopped working after a bit over a year. I thought it was a fluke and bought a second one. That one lasted me 8 months. The company claims this is normal and won't give any kind of refund/credit/etc--they say it's not defective. If that's the case, then I strongly recommend NOT buying this unit. It should definitely last far longer than that--I only used mine approx 4 hrs/wk while they lasted and I consider that light use. Good luck.
