I have used MSD products for years with no probs. I just thought I would let you know I had a 6 AL fail the other day, so I boxed it up and sent it off to El Paso for repair. They called me about a week later, said it was fixed so I payed the $38.00 over the phone for the repair including shipping and it was on my doorstep the very next day. Works like new. I call that great service and a bargain.
