The telescopic mechanism with the handle is great and easy to use for self defense purposes. I put it on the water bottle slot on the left side of my backpack, so that I can swing the backpack across and pull it out with my right hand quickly if needed. Much easier to carry around than the Walking Stick model. However the actual umbrella function leaves much to be desired. The mechanism to open the umbrella often gets stuck, and the canopy doesn't fully open. The canopy is also much smaller than my other $20 mini umbrella. Recommend carrying another umbrella in addition to this if it's actually raining, especially since you can't strike with it if it's opened anyway.
