I've used FreshPatch for over a year now and it's been fantastic. The grass is big enough for my two Maltese dogs to use and it stays fresh for about 3-4 days -- even in the extreme AZ heat. I've only had about 4 instances in the past year. A couple of times the FreshPatch seemed to be attracting ants and a few other times the grass smelled terrible. Since I get a FreshPatch every week, I'd say that's a great success rate (93% to be exact!). I also really love the account management interface, only wish I could pause delivery if I'm going to be out of town. Customer service is awesome too. A MUST for dog owners in apartment complexes!
