I think the concept was great but execution was poor.  There is a rather bulky square box with the solar panels to make this umbrella light up.  Unless you plan to run out and remove that every time there is a wind or rain storm this isn't very practical.  Most people just leave their umbrellas outside and forget about them.  On top of that ours arrived damaged.  We'll be sending it back.  

Pros: concept
Cons: solar panel connection
