To add on top of brother's huge-girth perspective, the LG Hanger system is good if you're into a linear and static hanging routine. It's a very common hanging vacuum system, which can be applied by the SiliStretcher, Stealth Stretcher, and many other All Day Stretch systems using vacuum cups.
As huge-girth pointed out, the Length Master has the hanger plates that add to the manual handle, the Power Assist, to further push the static and linear hanging method to a dynamic pull and stretching method. We discuss the bundled stretching methods quite a bit, and the bundled stretching adds the variable approaches that break down the tissues faster, such as dynamic pulling forces, various angles of pulls, and different combos of contortion forces applied throughout the routines. The Length Master has a learning curve for wrapping and plate mounting, and that can be frustrating until the user gets everything dialed in. Same for the vacuum cup system. It takes a bit of a learning curve, but you have to take a few steps back, and then think about static-linear systems to a dynamic system. The learning curve is practically the same.
