AbcoSport Golf Putting Green Turf Mat

Fun to play around with, but can't be used seriously. The mat does not lay flat and has many bumps and groves. I tried using a hair dryer to heat up the rubber mat slightly while folding it in the opposite direction it was folded in the box. This helped flatten it out a little, but the ball still bounces down the mat as it is hard to get it to lay completely flat. The balls also don't ever roll all the way down the track and frequently get held up in various locations so they don't return. The quality of the materials seem low for the price.
