Bought two of these for the low price. Charged them for 8 hours before use. Read the quick start guide and they both synchronized quickly. One to a motorola v3r and one to a v3t. Reception and distance are both very good. I don't keep it on continually and my battery has gone the last 6 days without a recharge. The large button is easy to find and the small button is not difficult. I have worn it in my right ear for 3+ hours at a time twice and had only mild discomfort near the end of wear. I have not used it with voice dialing so I cannot comment on it. I have yet to drop a call, even with the phone 10ft away. Volume is decent with the top down in my convertible in traffic at 40mph. Great for entry level headset.
