I purchased the Festool Carvex 420 EBQ Jigsaw with the accessory kit and when I opened the jigsaw sustainer I noticed that the package of blades that came with the unit were opened, but the unit didn't seem to be used. I have purchased 13 Festool products and countless attachments, and accessories and all of those products came with the contents completely sealed. Maybe the 420 had been tested using one of those blades, but I now wonder if this could be a reconditioned unit, or one that was returned to the store by a customer prior to the 30 day mark, then sold to me. Since none of my other Festool equipment seemed to be "individually tested", I'm leaning toward the 420 being a reconditioned or returned unit. If anyone has additional information on this subject I would appreciate their input.
