This is the best grill. It was not difficult to assemble. I purchased this to replace my old genesis II that I have had for over 25 years.  We use it at least two times a week nearly year round.  It heats up quickly and I love the sear zone for steaks.  I even seared a slab of ribs and it worked perfectly.  I purchased the griddle and pizza stone and both work great. The lighted knobs are a nice touch.  The meat probes are great to have so you never have to open the lid.  I wish there were four probes but I have a iGrill that I use when I need more probes.   My wife could not believe I wanted the side burner but I use it to make popcorn with my Whirley Pop popcorn maker.   This grill is well worth purchasing.
