I just got the grill setup.  Took me 2 hours so about what they tel you to expect.   The only downside that i see (which was an important part of my reason to purchase) is the power for the Weber connect.

It includes a hardwired option and Weber comments all over the other reviews that it’s designed to also be used with a battery pack. I (wrongfully) assumed this was included.  It is not.  I still can’t find where they even list compatible battery packs (or where to find it.). I didn’t want to hardwire and it looks like I’ll have to.  Bummer.
