Review on ScanGauge SG2 II Ultra Compact 3-in-1 Automotive Computer - Real-Time Fuel Economy Digital Gauges, Black, 5 Inch by Scott Spoja

I bought this to keep track of important things for my 6.0 liter power stroke diesel engine. Engine oil temp, engine coolant temp, fuel injector control module voltage, turbo boost, etc. Everything worked great and I'm very happy with it. Keeping track of miles per gallon is easy, but most importantly, I once had a problem with it when it wasn't reading information. I don't know if it was a truck problem or a scangauge problem but I called the company, got A LIVE PERSON IMMEDIATELY and didn't know what to do with myself. I asked to be moved to support and she asked how she could help me. I explained the problem I had and they sent me a new one, no questions asked, no receipt, nothing. It turned out that the same day everything worked again by itself and I gave them a new one back. When they returned it they called to make sure everything was ok. This is how you get repeat bookings and a following. What a great product and a great company behind it!
