Review on 🏌️ High-Performance PUTT-A-BOUT '360' Putting Mat, Emerald Green, 8ft x 18in (Model: 57P1808930) by Jason Staggs

This mat is $20 so I shouldn't be too critical but I'm returning it. It's still crumpled at the edges after lying flat for 24 hours. The whole thing is just a piece of green felt with very thin rubber underneath. No outside edges or anything to keep it flat and straight. After using it for a while, I realized how useless it was not having measurements or lines on it. I've tried measuring our distances with masking tape, but the center line is what I'm missing to see how far my shots are off center. $50-60 refund with all the stuff I really want. Lesson learned trying to go with the cheapest on Amazon.
