Review on 🧪 Enhance Trailer Safety with WATERWICH Heavy Duty 7-Way RV Blade Connector Tester by Marcus Consumers

I received this tester today and decided to check if it works. Before trying it on my car, I noticed that the packaging seemed to snap together quickly. I opened the box and examined the tester. I immediately noticed that the device was scratched and upon closer inspection I noticed that someone had disassembled and reassembled it, tearing off the screw heads and also damaging the case with a large screwdriver. Still, I decided to see if it works. I hooked it up to my car and the 12v light came on, tried the left and right turn signals and all the lights are flashing, tried to test the unit further but it doesn't work. It seems to me that someone else bought this device and didn't work, so they took it apart, damaged the device and then returned it to you. Apparently you lack quality control because it was sent back and now I have this worthless piece of crap! Attached are photos of the damaged device. One of the screws also snapped off and rusted! This is Revain's favorite product! Are you kidding me! I'm sending it back and expecting a full refund. I don't want any other of them!
