Review: Worked great, didn't even need the instructions - Plugged it in, messed with the settings for a minute or two, and then was up and running getting the Wh that a mission critical device used overnight. Love it. Only bad thing is that it's slightly more expensive than its comparable items, but for a device that actually works, I'll take it.
Review: Shuts off intermittently. Display is hard to read in low light. - shuts off intermittently. Display is hard to read in low light.

### ⭐⭐⭐⭐⭐ Easy to use
*by P***Z on June 7, 2021*

I like this unit. It monitors current and wattage. It also provides incoming voltage, frequency and cost. I do not have much use for the cost function but have been using this unit to monitor a cluster of plugs for a computer and various accessories.
