Auto Pump with Digital Smart Timer

Gamechanger. Far more convenient than a hand pump. Makes interval pumping a breeze. Holding pressure is done automatically. Does not have a timed zero pressure between intervals though. Pressure comes up fast and is a bit tricky to stop at your target pressure. Takes a bit of trial and error to get comfortable with it. Overall a great purchase at an economical price.

The first one I got had a battery issue, reached out and got a replacement and absolutely love it. Makes for convenient sessions.

Have not used it much yet but seams to be a good product
