What People Are Saying about ColorReader? “This device is incredibly easy to use - and it’s dependable.” John Metz - Haddon Painting “I love it. It cut one hour of time off my desk.” Debbie Deutsh – Interiors by Cornerstone “In this industry, time is money. If I can’t get the exact color they want, I’m losing time and material costs. “ Jon Ipock – ProTastic Painting “I have not stopped using it in matching colors to fabric and wall covering. It has saved me so much time in trying to match with paint chips.” Vincent Wolf – Vincent Wolf Associates, Inc. “There are many contenders in this field, but this in my opinion is the only one that provides the best balance between accuracy, ease-of-use and price. Whatever color you read with your ColorReader will be matched against those fan decks and the best matching returned. This is a much better alternative to purchasing multiple paint samples and trying them out, and is in my opinion the best bang for the buck.” Amazon Customer “Bought this (the lower cost one) because it seemed there had to be a better way than trying to match paint swatches to what is on the walls now. Setup was straight forward, and the app is fairly easy to use to take readings. The device accurately identified a swatch that I had, and it was straight forward to take multiple readings of the long ago painted walls in our old house.“ Amazon Customer Terms & Conditions: https://www.datacolor.com/legal/us/terms-conditions/ Privacy Policy: http://www.datacolor.com/legal-documents/colorreader/privacy-policy/
