Awesome VIN scanner, easy to use, you won't go back! Bad reviews clearly not dealers/used car managers. You can scan, or work from actual auction run lists perfectly organized by lane to avoid scanning vins all together. Everything you need on one screen: Carfax/Autocheck, book value of your choice, auction reports, auction announcements. Makes buying at sales easy. Saves time by automatically grabbing all vehicle info from auction data, including current mileage, color, and announcements. I've been a subscriber to blackbook's app for years and don't get me wrong, it was great and a huge advantage over a paper book, but this definitely takes the cake. I did demos of this and "laser appraiser"(same subscription price) in Jan 2013 before choosing this. No contest. I signed up for $99/mo - $50/month/book of your choice(blackbook, kbb, nada, galves, or market reports). Must pay for atleast 2 books to get Carfax/Autocheck integration, uses your existing subscription. This is a must have for volume buying.
