I'm using mine regularly recently. I think it will be helpful for a lot of stuff. Practiced a lot of standing M1's today, along with a couple other passes. I think it will be as useful as I make it. I'm not sure yet if it's worth the money. I have the pro-boxing submission master as well. I can definitely say, it's made well and very durable. It isn't the real thing, but I think it will be useful for some stuff. I'll keep everyone updated as I come up with better uses for it. It's definitely good for practicing things like rubber guard, just to memorize the paths.
