Great, does just the job
I was concerned to monitor my PC power usage as it is left on 24 hours in order to do backups etc. I used a C13 'kettle' plug extension cable, which I cut in half and then wired both end to the monitor so that I can put it in line with any device that uses a kettle plug power lead. The accumulated KWh seems to be accurate.

Good Visual Monitor
Installed quite easily - screen a bit difficult to read if you are at the wrong angle but seems to show the required readings okay. There is a back-light too.

30 day warranty, failed in under 12 hours, can’t get in touch with company or Amazon, Avoid.
Ordered on 10 December 2021, and I must admit it’s taken me a while to actually get round to fitting it, but I finally connected this in last night and it’s not working by the time I looked at it again this morning, so it’s barely lasted 12 hours. The backlit background no longer works and the lcd screen is only visible from an angle, it’s as if it’s running out of batteries. Very unprofessional. It would seem that it only has a 30 day warranty period and Amazon make it very difficult to get in touch with the supplier as they are not listed. It’s almost as though Amazon don’t want to know either. Save £20 and buy a different one.

Not happy with failure after 6 months.
Had this item about 6 months now. Worked fine for about 4 and the last 2 months the unit reports utter jibberish. Connected to a 230v site and it’s reporting between 68 and 71 volts. Not impressed with the one I have purchased.

Gutes Teil zum Einbauen in Geräten mit Netzspannung zur Überwachung.

Der Einbau und Anschluss ist problemlos, die Anzeige gut ablesbar, die dargestellten Werte erstaunlich genau. Die Werte unterscheiden sich kaum von einem im Zählerschrank verbautem Profigerät. Ich habe die Anzeige in unsere Wallbox eingebaut. Über die Haltbarkeit kann ich noch nix sagen, das Gerät ist jetzt seit einem halben Jahr im Dauereinsatz. Bisher nix negatives.
