We have the best espresso machines for home and office use.
"Home use" pertains to relatively small volumes - what a family is likely to use. These machines are NOT meant for commercial use, where you'll be making 50+ drinks per day. If you are selling espresso-based drinks, or make large volumes throughout the day (as in many offices), you will need commercial equipment. Commercial equipment is more rugged, and will be NSF, ETL, or UL certified. You should ask the local inspector what is required before purchasing for business use.
