The Pulsar is a dripper born from a collaboration between NextLevel and astrophysicist **Jonathan Gagné**. This dripper employs a **no-bypass brewer** design and features a valve to control the flow of extraction. By using the valve, it's possible to freely adjust the flow rate while maintaining a consistent slurry (mixture of coffee grounds and water) during blooming. Coffee consultant **Scott Rao** has said, "The Pulsar is my favorite hand brewer and is also perfect for travel." It is in the condition shown in the photos. The box is no longer available. This dripper has not been used much, but please understand that it is a used item.
