I love
mine :-) It's so clean and neat in the winter, the dogs use it exactly the same way they use normal grass - racing around, going to the loo or sleeping on it and it still looks exactly the same as it did when I put it down.
The negatives are...
Price, but it seems to last forever.
Cleaning, unlike normal grass you do have to disinfect it or it smells. It doesn't take long though - just the same as hosing slabs down. I use whatever cleaning materials I have - mistral disinfectant (from ebay) or cheap bleach. It needs done every 2 or 3 days in the summer and every few weeks in the winter.
Installation, it's really really heavy!
The positives are no more cutting, no more mud and always looks neat :-)
I only have it down in my small back garden, if I could afford it I would do the front garden too but it's huge and would cost several thousand :-( Maybe one day :-)
