"I am very happy with SLC Gauge, the blue LEDs look great and in the past 6 months of ownership I have had 0 problems" 
E. Lin, satisfied SLC Gauge customer

"Accurate when compared to much higher priced controllers, easy to install, and reliable"
G. Craig, satisfied SLC Gauge customer

"I already had a wideband but it was constantly failing on me, their tech support kept telling me to do another free air calibration and put the blame on my virtually new sensor, nothing worked and I gave up. I decided to buy SLC Gauge and I am 100% happy with the product, no more headaches"
M. Lowe, satisfied SLC Gauge customer
