      Easy to install - just plug into your power plug - low costs - starting at around 300€ - and return on invest in 1-2 years. That‘s a quick win.

      However, you should have more recent power cables installed in the wall, not old ones from the 60ies. Or put differently, if your cables in the wall get warm when your hair dryer runs for half a hour - don’t do it.

        The article says they cost 400-800 Euro and the poster at the top says they generated 380kWh which is about 100 Euro’s worth so seems more like 4-8 years. Still likely worthwhile of you can get that and they last significantly longer than 10 years, but not a no brainer everyone should buy.
