Most ranges that i go to do not offer a place to practice uphill, downhill, ball above and ball below the feet. This is the ONLY may that is portable providing this kind of lie. You could build something with a standard mat and wood frame but it would be much less mobile and heavier. Today i ordered another mat to try a see if they are effective to create a steeper slope to play with my aim. Make sure that for longer storage, lay it down flat to maintain its shape. I am surprised there are not more like this on the market because it is more like the course. I bought my 1st on 6 months ago and it has held up great, i bought another to see if it works stacked for steeper slopes.
