A few years ago, I invested in a Davek umbrella. Two days ago, I accidentally left mine at work to only find it gone the next morning. I am so bummed. It was the best umbrella ever. Strong, durable, wouldn't flip when a strong gust of wind came, and kept me so dry. I will miss it.
But in doing some research to buy a new one, I found out they are guaranteed for life. And apparently if you lose it, they will give you another one for 1/2 price. That's pretty amazing. Except I never registered my old one so I can't get my next one half off. Lesson learned.
If you do the math, it's worth the investment. I highly recommend. Off to buy my replacement!
