Review on 🎶 DIKAVS DC 15-24V 15W Mini Music Tesla Coil Plasma Speaker Loudspeaker - Tesla Wireless Transmission DIY Kit (red PCB) by Joe Michels

Never worked for more than 10 seconds and then hardly ever. Not sure why it failed. There doesn't seem to be any troubleshooting guide or help for this product. Useless junk now adorns my rather odd electronic kit display. 24V power supply? For real? Most people just aren't going to sit around and do this. It needs to be redesigned to use the standard 12V DC and a more functional circuit that doesn't turn on all the lights indicating everything is working fine when it's not working at all. This product's image shows a roll with a wider unwound portion at the top, but my kit has a directional arrow sticker clearly showing it's pointing backwards. ? Pooh. I'll try to turn it around. I doubt this will improve the situation.
