I have been a senior Software Engineer for 6 years now. I would like to take this opportunity and express my total satisfaction from your state of the art product. Your product met my needs entirely and is proven to posses many characteristics and qualities that I was looking for. I am also impressed with the flexibility of your product and its ability to answer several of my needs at once.
In addition the service level and support that I experienced is one you should be proud of. It looks like your company is using the marketing concept where the customer is in the center of all activities. As you proven to know, a company's offering is not only the product itself but a total solution which includes the service and support as well.
I can conclude and say that you did not only meet my expectation but by far exceed it.
