vinyl/leather repair kit

Does anybody know if this really work. When i bought the car i promised i wasn´t gonna smoke in the car but after the first month i started doing it and this weekend i burned the passenger seat, now every time i get in the car the first and only thing i notice is those 3 fu***ng holes and i feel like an stupid as*hole. Has anybody used this kit? Does it work? Is it noticeable?
