We purchased the refurbished toughbook for automotive shop use. I was a bit leery about buying a refurb unit due to a prior bad experience with another vendor. The unit arrived in better shape than expected. It arrived quickly and we were impressed with it's functionality and abilities. The real test and most impressive part of the purchase came a few days later when the unit would not boot up. My heart sank,here we go again. We called the tech line and surprisingly a person answered who was knowledgeable and courteous. He apologized for the issue and began instructing my technician how to trouble shoot the problem. Within a few minutes it was determined that a stick of ram was faulty. He instructed my tech to remove the one stick of ram as the unit would function with one of the 8 meg sticks removed. Once that was done the unit started and functioned. The person then promised to ship us a replacement immediately, which he did. The replacement stick arrived within 2 days. That's how service should be. Excellent company to deal with and we are looking forward to purchasing another unit from them. It's nice to see a company care about what they are selling and are willing to stand behind their product. Great job!! Highly recommended.
