TESTIMONIALS

• “Orders are always taken, filled and shipped on time. Check Corporation is a good source of information on cars…Warranties are always handled professionally… Sales makes sure we always have information to sell product.”

  - Dick Olliges, VIP Distributing - St. Louis, MO

• “Install went well. I wish you had included the Tap-a- Fuse so I didn’t have to go find one. It works well. I would like to turn the heat down a little, and would like it to shut itself off if wired to a hot fuse.”

  - Dick W., Delaware

• “Excellent Customer Service, technical support and, above all, high quality parts.”

  - Jerry Davidian, Dura Mend, Inc - Parma, OH
