They are absolutely amazing! I brought in my vacuum which wasn't working, and Manny fixed me up in less than 30 seconds. Swapped my defective part for one of their new ones, and said they'd process the warranty for the old part so nothing for me to worry about.
You don't think about investing in a vacuum, but if you want a high quality vacuum cleaner and a business that stands behind their product, ABC is THE BEST. they have all my future business.
