I have one of these umbrellas I purchased about 10 years ago, and don't know how I ever did without the auto open/close feature.  It is a lifesaver when your hands are full, which is always when I'm out in the rain.  I hate for my husband to take my umbrella, fearing he will leave it behind somewhere.  I was delighted to find these on Amazon, and I just bought another one for my college-age son, and he was so happy to have one that he can open and close with one hand.  You do have to finish the close manually, but that's no problem since you can collapse it with one push of the button and walk inside to stay dry while you complete the process.  It is large enough for plenty of coverage too, yet small enough to carry inside a backpack or larger purse when not in use.
