THE MORPH 30” Roller Extension Kit provides a quick and simple way to combine two MORPHs into a single, 30-inch foam roller so you can incorporate even more movements into your foam rolling practice. MORPH ROLLERS sold separately.
I was a little disappointed in the disk that gets inserted between the two rollers, because it's just foam and not very rigid and does not seat very deep into the cavity. It falls out WAY too easily, especially when assembling. I can see the edges have a potential to get rounded off after future use. However the jacket seems to hold everything together and when I actually rolled with it, everything moved as one and it didn't hamper the rolling experience. Just would like to see better material used for the disk.
Works as advertised. I roll every morning and it helps loosen up and keeps me straight. If I do miss a day I can feel a difference.
