My son and daughter both ordered this battery for their Razrs.And reported that it worked well for them at an unbeliveably low price.I was sceptical, but decided for $ 4.11 I could afford the risk.I it one tenth the cost of the outrageously expensive batteries fromBest Buy and Verizon Stores.Logically, the price seem reasonable since it is only the size of a couple of AA batteries.So far it Seems to work very well.Can't speak to long term longevity, but so far it holds a charge for at least as long as the OEM.$4.11 vs $ 40.00
