Review on Omix Ada 17215 02 Tachometer by Steve Yang

I hate to write bad reviews but I'll skip this one. I actually have one in my jeep and it was doing several hundred rpm. I bought this to replace this one and it's even worse quality. White backlight that doesn't match. Then the touch reads up and reacts slower than the mollas. It doesn't actually register anything above 3500 rpm and takes 14 seconds to return to 0 or idle speed. If anyone has any suggestions on where to get a quality cj accurate aftermarket tachometer to fit my jeep let me know.
