I like the product, however none of the supplied ear piece adapters fit my ear. The earpiece would continually fall out regardless of how I positioned the adapters. I ended up using a Jabra ear gel from an old ear piece I had. It fits the Samsung unit but it has to be positioned just right so it doesn't block the sound from the speaker. If set up just right it seems to work alright, but I certainly wouldn't buy another one. The function is good, but the fit is terrible.
