It is a great attachment to an already amazing grill. To install it, it's literally only 3 screws on one side and then you attach the motor to the other side. Then slide the bar in and it works like it should.

My only word of advice is: If you are going to do a chicken or anything that needs to be "tied together" with cooking twine, i would tie it AFTER you put the meat on the metal rod. I tied up my chicken nice and tight, but then after i put the metal rod through the chicken, there was parts of the chicken that would hang low or was loose. If you tie the meat after you stick the rod through, you can make sure everything is secure to the metal rod and the two metal spikes are secure and ready to go.

Otherwise like i said, a fantastic attachment. Can't wait to roast a turkey for thanksgiving!
