Beam Built-In Vacuum & Security

I purchased a new built in vacuum 1 1/2 years ago. The power head became intermittent. I took the head, hose and wand back to the store and the service technician tested the unit in front of me, found the problem and replaced the unit, all in about 15 minutes, the whole time with a smile and pleasant attitude! Wow, you just don't see service like that these days. Thanks so much!
