I have been very pleased with this putting mat. It was as advertised, The mat rolled out reasonably flat and was completely flat within the first 4 days. The gradual increase in incline within the last 18 inches is a great training aid in forcing you to learn to make a firmer putting stroke, which not only helps insure that your putts reach the cup, but will also assist in holding the putting line. I recommend this product.
Glad I purchased this par 3 putting green. I use in frequently inside my home. Love the quality and it's fun using inside my home. It's also easy to roll up and bring back after having company. Now, if only it improves my putting? I'm looking forward to my next golf games.
