I've been using this earpiece daily for a bit over a month and have found it to work quite well for my situation. I'm a chauffeur and needed a replacement for my previous earpiece (supplied by my employer).Time will tell how well this one will stand up to the rigors of daily use, but so far it's been very reliable. Once attached I hardly know it's there. It's loud enough for my needs and everybody I've talked to says they can hear me fine. All-in-all a fine value.
