This is surprisingly good for the money. The turbine seems almost frictionless and will rotate at a very low wind speed. Though it's difficult to check the calibration accurately without building a test-rig, walking with it seems about right. The standard functions are all there, and the device seems solidly built to last. Maybe best to have a case for it if it's in your pocket, though.
