Put this out on my paved patio.  Was able to put this together in an afternoon but needed a second person for a few items.  I highly recommend an ratcheting driver as an extra tool here or your hands will be very sore.  The extra 2 feet over a 10x10 is really nice.  I've had it up for several weeks and a couple of parties and it has worked great with no damage or problems.  I got a few misters for it as well and highly recommend those.  

Pros: Easy to put together. Good shade. hasn't blown over. 
Cons: Included tools suck. Instructions could be a bit better.
