Review on CHINLY Bluetooth Twinkle Sound Activated Crystals by Brent Walker

When I bought this everything worked so we started installing and disassembled my entire truck. On day 3 of the installation process we reinstalled the headliner and when we plugged in the LED light engine it just flashes very quickly and then turns off. The circular disk continues to rotate without light. I called Revain and they told me to contact the manufacturer directly and wait 3 to 5 days for an answer as to whether or not they will replace it. I spent $350 on it and 3 days of installation work. My entire inside of my truck had to come out. Now I can't fully assemble my truck until I have a spare engine. I'm very frustrated that a 3 day weekend project isn't turning into a week, maybe more.
