Just got this Weber Searwood XL600 last month.  We used the BILT App for assembly, took us approximately 30 minutes to assemble.   Downloaded the weber app and followed instructions for start up. No trouble, with anything!  

So far, amazing in every way!!  To date, Tomahawk steaks, chicken, rotisserie bbq'd pork loin,  and ribs.  Can't pick a favorite,  because everything was delicious and perfectly cooked.  I followed some recipes on the app, and also just cooked indirectly...both ways were amazing!  The ribs I made today were the best I have ever smoked.  Can't wait to do turkey!  Very impressed at how little pellets that it burns.  Definitely worth every penny!
