Review: Handy bit of kit - Purchased to take fan pressures and drop tests does the trick perfectly
Review: Good for the money - It's comes with a neat case and spare tubes. However it doesn't interface with normal sized gas tubing as hoped so a bit of looking in the spares for adaptor put it to use for testing. The record feature is useful but does switch off ifledt too long. Overall worth buying
