I had a microwave and dishwasher installed on two different periods of the same morning. Microwave install went fine without much problems. He cleaned up his mess and was out in a timely manner.
The dishwasher install didn't go as smoothly. The installer seemed a bit in a hurry and didn't do as professional of a job. He made a bit of mess and didn't completely clean up the mess he made. Very disappointed in that. One thing I didn't like too much was the fact they suggested they replace a connection hose. I am okay with that and wish when I initially purchased the item, it came as part of the package. I was not to happy to write out another check for that part.
