I bought this to replace a Motorola unit I lost on a flight, partly because I prefer Nokia (Married to a Finn, so I'm biased, though SHE bought me the Motorola as a gift). Worked fine for a few weeks, then suddenly wouldn't take a charge, turn on or anything. I let it sit while deciding whether to replace the battery or send it for warranty repair/replacement. Then, yesterday, I plugged in the charger and, surprise, it started charging and now it works! Go figure. The only thing this lacks is the holster and medallion clip as alternativevs to carry the unit like the Motorola. But, for $20 less, I can live with that. Actually, the unit fits in the "M" holster.
