Vagelis Fatseas

Been using it for a couple of weeks now. The scheduling works well and it’s nice not having to think about turning things off anymore.

Stacie Gerbers

Ich hatte keinen großen Unterschied erwartet, aber ich habe tatsächlich eine leichte Reduzierung meines Stromverbrauchs festgestellt. Simpel, aber effektiv...

Maria Olofsson

The app is straightforward and easy to use. Took me a few minutes to get everything connected, but after that it’s been smooth.

James Wilson

I bought this mostly to manage a couple of devices in the evening, and it’s been doing the job well so far. The scheduling feature is probably the most useful part for me — I just set it once and don’t have to think about it again. The app is simple, nothing complicated. Haven’t tested all features yet, but for basic use it works exactly as expected.

Elias Nordlund

Took less than a minute to connect. The app is simple and works perfectly. I love being able to turn things off when I’m not home.

Ordered this to manage some devices at home and it’s been working really well. Setup was simple and the app is easy to understand. I mainly use it for my lights in the evening and it’s convenient not having to think about switching them off. Delivery to Austria was also fast, which was a nice bonus.

Stefan Andersson

Overall, I’m happy with the product. It does what it’s supposed to and the app is fairly easy to use. It did take a bit of time to connect the first time, which was a bit frustrating. But after that, everything has been working well and it’s been very convenient in daily use.

Jag köpte den här för några veckor sedan och är nu tillbaka för att beställa igen. Har varit riktigt nöjd hittills. Enkel att använda och gör exakt det den ska. Har även rekommenderat den till familj och vänner, och flera av dem har redan köpt en också.
