Charles, nice feedback but I don't 100% agree. It wouldn't "deteriorate" that noticeably with 30 mins difference, and the temperature is really personal preference at the end of the day (even though my preference will be 120°F) and for the wattage issue. You need to find out circuit structure of your unit and try use some other circuit under less traffic.
Price wise, Debbie purely looked at it from ordinary home cook's perspective so the price is quite important factor I guess (but since this was a review for the circulator, negative opinion on the vacuum sealer was completely unnecessary. your can always use "ziplock" method or there are tiny vacuum sealers option as well.)
