Several years ago I ditched my 17lb vest/CPU unit for travel and purchased a chargeable hand-held massager/percusser from Brookstone. Cost was approx $200. The handle grip enables me to easily reach my entire back area. This has served me well for traveling, can be carried in personal carryon bag & has only been questioned once (recently) by TSA. Because of lithium battery, it must be carry-on only.
