Great product
I would not say a 2,-3 hour build. 3 people for the first 3 hours, yes the temp was about 50 degree, then 2 people for another 2 hours. Yes, we are more anal retentive than usual. The instructions are okay not as crystal clear that I had hoped. Plan on silicone to secure a few panels. Over all. Very pleased, although I can see wind more than 15kts being an issue during the build.
