Please note

When returning to us material considered by you to be defective, please imperatively tell us in some detail what the problem is. What does not function? How did this manifest? Did it happen right from assembly on or later after some time of run? Sentences such as "does not work" are absolutely useless! Experience shows that most returned materials are perfectly OK. You can save time and effort for yourself and us by contacting us before you send something back. Often the problem can be solved by communication, but surely not with sentences like "does not work". 

When communicationg as a fitment problem
with some newly delivered system please see what we need to know other than the 3 words "does not fit"
