I am thoroughly impress after first session. I feel it around my waist. I personally feel an energy boost after first use. Device feels sturdy and could handle me at 5 ft. 11 inches at 190 lbs. I am thinking of getting one for my retired mother for low impact workout.
I got this one for travel and work. I’m impressed by how strong it is. I have the pro for home and expected this to be significantly less strong. Instead it’s small but powerful.
