This issue has not yet been resolved and I'm confident it will be; however, when I received the product it was badly damaged. The box had been dropped and multiple corners are bent. The box I received (a dispenser for automotive hoses and lines) is in working condition, but damaged and I hate to pay for something new that's badly damaged. I would prefer to receive a replacement product in good working condition if possible. Jeff
