Title: A messy job at best.
Review: This cuts great circular holes and it's easy to use. The only bad thing I quickly noticed is that if you are trying to cut in a circular hole in a ceiling the airflow that normally keeps the cutting area clear blows the dust everywhere. It makes a big mess and throws more dust and debris in your face then using a circular saw or sawzall. It only rates 2 stars.
