I have one of their bags and with 3 filler bags. They've made it through 3 moves and a deployment. I do not regret spending money with them. I have not used any other their programming and was unaware they even offered it.
I have the smaller and larger bags with a variety of filler bags, and I bought the exercises poster. I travel a lot and they are handy to just through in the truck with all my other junk. I also use them at the range and in the DT room with students. They were the first home gym purchases and would be if I had to do it all over. I have the app, but I haven't really ever followed their programming to the "T". I just use it for inspiration... or torture.
