Review title: Many useful features
Product review: This product is truly amazing. I have been using it to measure my power usage of devices at idle, in power saving mode, and under load to determine my power usage at each stage. This device offers many options usually only found in professional instruments costing much more money. In addition to volts, amps, and watts, this unit also measures power factor and volt-amps. It will also measure power usage over time, so you can use the device to predict the cost of usage against your electric bill.The one feature I see lacking that my traditional ammeter has is peak hold. This would be useful to see the maximum power draw of a device. All things considered, this device is well worth 10x the price for the functionality that you get with it.
