Review on 📺 Smart TV LED Backlights with Alexa and Google Assistant, Easy Installation for 32-65 inch TVs, 6.56FT LED Lights for TV, 16 Million DIY Colors - Perfect for TV, Computer, Bedroom, and More by Kelsey Hoss

I was very happy to install these lights (I bought them on Prime Day) but between school and work I didn't get a chance to install them until after the return window was over closed. I plugged it in, held the "on" button for more than five seconds several times, but the light never came on. I checked that everything is plugged in properly (it was) and tried other outlets and USB plug adapters...nothing. I DEFINITELY regret not having tested them sooner (at the time of return). Can't comment on Alexa adhesion or integration... no point sticking them to anything if they don't work (although the backing of the tape peeled off on its own when received). And (obviously) I have no way of testing this with Alexa.
