These little machines are ultimately throw-aways. ( I have never bought a top-line unit) Buying and coping with bottom line units is challenging. Seems like the "whole crank" feature is misplaced on this marginal model. I have a box full of scrap tanks, magnetos, with little prospect of future use. But the click-it has helped with the hedge clipper, and I have used the chopper blade on larger branches . Also have broken a car side window (gravel) and now a second story double pane window (my bad weeding among rocks). Be careful how you tilt the unit !!
