It took about 10 minutes to install this heat deflector contrary to what others have said. HD instructions are only a guide. Looks good on my 2010 Fat Boy Lo. Too early to determine how well it works but should help with the heat.
As I've heard many times before about this item "I don't know why I waited so long to buy it". What a difference it makes, especially for our Arizona summer temps. Easy to install, done in about an hour.
