Nice size umbrella, easy to operate.  However, the material frayed at the edges after about a week, and the sleeve which locks the arm in place while open is plastic, and split from the weight of the umbrella in just a few days.  I had to wrap it with duct tape to hold the umbrella up.  Last, it definitely needs a weight, as the umbrella is too top heavy when opened and falls over without weight on the bottom.  Nice design, cheaply made.
