I bought this power strip to help me monitor electricity usage in an off-grid situation. I would not recommend it for this purpose. For one thing, the monitoring capability is minimal. You can monitor each outlet individually, but you can only see three numbers for each: how much is currently being used, how much has been used for the day, and how much has been used on average (but for what time period is unclear). There is no historical data available, so you can't evaluate usage patterns or identify spikes without constantly monitoring the app on your phone.The other downside probably should have been obvious, but I didn't think of it before I purchased it. Which is that the power strip itself draws power, even when nothing is plugged in. I didn't measure how much it was drawing specifically, but it was enough that the power strip was getting quite warm to the touch from just sitting idle, plugged in. It wasn't quite uncomfortable to hold, but let's just say it would work nicely as a hand warmer. It makes sense, when you think about it, because there's a WiFi radio in there that's running all the time. If you're in a normal on-grid situation, this is probably not much of an issue, but when you're counting your kwh, you don't want your monitoring equipment adding to the overhead.It also, really does need an internet-connected wifi router to connect to. It's absolutely mandatory to set the thing up. It was strange, because when I plugged the power strip in for the first time, it shows up as an available wifi on my phone, and you can successfully connect to it. But this connection is not sufficient for the app to work. It can't find the power strip even though it's connected directly to the power strip. I then tried to turn on the hotspot for my phone, and let the power strip connect to that, but that also doesn't work. You and the power strip must both be connected to a third wifi network, then the app works as expected.However, all that was mostly due to the fact that I was using the item for a purpose other than what it was designed for, so I can't fault the manufacturer for that. All in all, it's a very solid piece of equipment, very high quality, good thick cord and good solid manufacturing. The app is well designed and easy to use It is a large power strip, probably 25% bigger than your normal, average, non-smart power strip, which means it's got lots of room between the plugs for big adapter- or brick-style plugs.The one thing that's poorly designed is the mounting holes on the back. It has two holes that are the typical keyhole style, and they are made in such a way that you can mount the power strip either horizontally or vertically, which is a nice touch. However there was an error made in the design process, because a screw will not slot into the narrow part, no matter which way you try to slide it. There's a small piece in the corner that blocks a screw from entering the slot either way. That's an unfortunate error in an otherwise excellently engineered piece of equipment.
