Love my SPX435!! The assembly instructions were clear n straightforward.   It took about 2 hours for 2 of us to assemble it. I've run a 30 mi ute burnin, cleaned n aeasoned the grates, and also downloaded the app, along with an impressive list of recipes.   I only cooked twice so far ( I'm out of town this 4th of July weekend), but it started and performed great, with easy start and uniform heat thruput the cooking surfaces. Impressive grill marks on burhlgers n steaks!     As I uae it more, I'm sure it has more to offer!
