    "The ease of installation was better than what I had anticipated. The programmer housing was an exact match to my dashboard, and the appearance of the unit looked factory installed. I have only had the programmer for a short while, but enjoy the fuel savings already."

    "The product was very easy to plug in and use. I was deceived by the information about the product because this product will not work with the 2008 Chevy Impala. Ultimately, I sent the product back which was very easy, and service was helpful. "

    "The Vivid Linq works great. Big difference in power for my 14-year old truck. It was just what I was looking for. The installation instructions were a little confusing, but the customer service hotline walked me through it just fine."
