I usually do the drills at the gym before a workout and they really dont take a lot of time. When i cant make it to the gym i will just do the drills at home and can get them in quickly particularly if time is an issue. So absolutely give it a shot i think you will enjoy it and get results. As to the radar having one gives you instant feedback, indicates what variations from grip pressure to turn and other factors have on swing speed. Most importantly i think it serves as a motivator to see where you are and encourages you and allows you to set goals and then know when you attain them. Its a great feeling when you instantly see the results and your speed is increasing . And i firmly believe this program translates to results on the course.
