Query: Overpriced, overengineered, and misleadingly promoted

Can't say these are worth the money; there are reputable 2400mAh to 2500mAh rechargeable AA batteries out there at half the price, by companies from Maha to Energizer. Also, the fine folks at Monster Cable are fond of threatening lawsuits to any company with "monster" in the name, including the job search site and a clothing reseller. Sending your money to a company with such underhanded tactics and a marketing division exponentially better funded than their research is your choice, but I would recommend in the face of alternative suppliers that you choose against it.They get two stars because I'm reasonably sure their product will not melt your device.(review title quoted from dansdata)
