Best Artificial Grass Surface Safety in Phoenix AZ

I have had this turf less than 1.5 years and it needs to be torn up. Basically it lays over when walking and no matter how much raking and maintenance I've done it just looks terrible. They sent out a rep and he even admitted it wants to just lay down after he combed it with a hair brush 20x! Their warranty department denied the claim. Never use this company or their products.
