I bought the one with wheels, and although I've only had to move it once, I'm pleased it has wheels, or it would have been too heavy.
I wasn't sure how long I could expect to keep a piece of turf alive, or if my dog would appreciate my efforts. My first piece of turf has now been growing for about 2 months and is perfectly healthy, and my dog loves it. I keep one end trimmed shorter than the other, as sometimes she likes to dive into deep grass, and this is the only grass in my yard. Very happy with my purchase.
