Review on THINKWARE TWA-SH Hardwiring Kit: Uninterrupted Parking Mode, Impact Detection, and Car Voltage Protection! by Bob Randles

After the product sat untouched in my office for several months (until I had time to install it), I installed it and it doesn't work at all. Tried to install with a backup. Install exactly as directed in the video, paper instructions. It does not work. Fuse current checked. It works fine there. After that tested. No electricity. defective product. A lot of time and money spent. I think I'm stuck. Either spend more money or just connect without parking mode. ***Update: I finally opened up the fuse box and found one had already blown. Replaced the fuse and everything worked. It's still a bit overpriced in my opinion and I wasn't happy about changing the fuse before I even used it and I had to spend all my time troubleshooting.
