I have a Big Moss. I custom ordered the size through one of the managers on one of the Facebook pages. It’s only about 6 feet long maybe 4 feet wide. That’s all that really made sense for my in my office.
It’s nice to get up while on the phone in meetings and hit some putts. I did 3 cup sizes which I kind of wish I didn’t do. The speed is okay, prob around 10-11. The backstop is just foam. I do like that you can stand on it and it doesn’t effect anything. I would kind of think it would be even better and maybe a little faster on hardwood or tile then on my carpet.
It’s a tough road to go down. Years ago I had the idea to build one in my garage. I can honestly tell you the platform is still the only thing built and every week I consider ripping it apart and saying goodbye.
I’d give the Big Moss 8/10 for what it is. I do think it would be more fun if it was 3x as long. And at least twice as wide.
