Hey Mark! First, I just want to thank you for getting the product shipped out in a timely fashion. That's a rarity with Kickstarters.
As for the cabana, it's fantastic! It's truly a breeze to setup and takedown. I will say that I was a bit lost the first time, because I was not aware that the sand spike was within the pole - I thought it was missing! Other than that, it's been a blast.
We took it up with us to Maine and a lot of people were intrigued about the product. Hopefully that will translate to some future sales. You mentioned wanting some pictures of the product in action, so I've got two linked for you below. I hope they can be of some use to you.
