Hi Uku. You can install it in every apartment - not important if owning or rental. Just change and be happy to save money every day. And you got it for free, just amazing - isn't it?

5/5

Light bulb has very accurate color rendering and gives great contrasts. Doest strain eyes like most cheap led bulbs with just leds and capacitor or PWM. Great for getting accurate adequate color. Very satisfied.

5/5

After installing two X25 filterswere installed in my living rooms wall sockets, the eletrical noise in the visible wiring and especially in my computer decreased notably. The noise also became more "coherent" with less spikes. I used an analog am/fm radio for detetcting the noise. Immediately after installing, I have also felt my muscles and internal feeling got notably more relaxed and anxiety decreased clearly. Installation process was very simple. Im happy, and ordering more of these. Visa
