I bought one of these, U212 I think over 10 years ago and I lost it. I bought another U 212 which I believe was a little shorter. The first one had a much better functioning umbrella. I’ve always been glad to have on hand, but I use the umbrella a lot. I have yet to use the umbrella for self defense except in training. I bought the heavier duty model hoping the umbrella would be better, but it’s about the same. I wish I had the old one.
