It folds for easy storage, it unfolds quickly for use.
Literally drop the snap pack in and lock in place! Simple!
Also, LOVE the edger feature, before, I used to waste fertilizer on parts of the street, with the edge feature, it only is used on my grass. Although the initial cost is greater than years before, I will use it forever with it's sturdy construction, and will not waste unopened bags of treatment anymore...BIG FAN
