The WEP200 I bought is a back-up for the one I already own. I lost the charger/carry case, so it was cheaper to buy another unit than to get just the charger. I had 3 Motorolas & 2 Plantronics before this one, and I am happy with the reliability of the Samsung. Sometimes I have trouble keeping it in my ear, but switching ears is as simple as twisting the ear loop. Plus with 3 different sizes of loops, its easy to find the perfect fit. The Samsung website had these units for more money than Amazon.com. E-Bay is cheaper, but when you buy cheap, you get cheap! Plus, I've had nothing but trouble with E-Bay. Amazon.com is great, especially when they offer free shipping on some items. i'll be back for future purchases.
