I have been using my new golf mat and birdie balls for about 4 weeks now and I absolutely believe they are the best training aid I have ever used. I try and hit them every chance I can the results are that I have lost at least 5 strokes a round.
I have the mat set up at the back of my driveway looking over part of my back yard with 3 targets to shoot to. By the way my 7 year old grand son uses the mat more than I do, we let him hit real golf balls for now but that won’t last much longer.
