Intended for office use, the UL Commercial listed B145 doesn't have a ton of additional features, like Strength Control or Temp Control.
Instead, it has a different take on functionality, leveraging a brew size selector knob.
It also has a convenient Drain Brewer function, but it isn't compatible with the reusable My K-Cup.
Intended for use in small offices (Keurig arbitrarily says less than 15 people), the 48 oz water reservoir will get the job done but will need to be refilled frequently.
Like all B series Keurig brewers, the B145 is the predecessor to the K series version, the K145, and has since been discontinued.
