Wow....rolling with this thing takes some getting used to. The snap, crackles, and pops that emanate from ones body when indulging in a little SMR with this baby are amazing. Be aware that being seen in public with this thing may cause some people to stare as they try and figure out if you bought it from Adultshop.com, or something like that....but honestly, this roller is like nothing else I’ve ever used. Beats the Rumble Roller hands down. Takes some time to adapt but boy, does this thing smash your fascia....get yourself one and feel the (temporary) pain.
In an effort to create our own rumble roller we filled the bottle with rocks. This does NOT work. I suggest sticking with water.
