To whom it may concern,

Alumco has been a supplier of MobileData Communications since 1993. In that time, Alumco has always made top quality parts for M.D.C. for a competitive price. Alumco communicates well with both purchasing and engineering. They have always helped us with DFM to help reduce cost. Alumco's on time delivery is exceptional; they are a supplier that you can count on to meet your needs. I would highly recommend Alumco as a supplier.

Sincerely,

Michael R. Rollins
Vice President Manufacturing
