I have been a customer of DASI for many years, and if you are looking for a reliable company with excellent training and technical assistance this is the company for you. I have never been less than completely satisfied with their employees demeanor and continuing helpfulness when I've had to reach out to them for assistance. On a scale from 1 to 10 they are a solid 10. If you have yet to encounter the DASI Experience I urge you to do so, you will not be disappointed.
