Very nice looking grill. Have only used once so far but worked great. Played with burners to see how hot it would get. I was amazed that temp went above 700 with all burners going! This will be great for steaks. I cooked a beer can chicken and needed to control the heat around 350-375 so after heating to around 500 I turned down two burners to low and turned off the other two. Temp dropped but had to only use one burner on low to maintain the temp. 
I'm pretty good with tools and building things. I've put up metal building, built many houses and remodeled even more. I'm a Mechanical Engineer and spent 40 years in construction and construction management. I think you would have to have put together dozens of these to be able to put it together in an hour. That being said, the directions are good, the pieces are made to align perfectly and taking your time and following the directions should not present any problems even for a novice but it might take at least 2 hours.
