You can find out more about the Lumo Lift here. It comes with a little charger that you can plug into your computer or a wall brick. I usually charge mine every night while I sleep, but it doesn't need to be charged daily. I've gone 2-3 days without charging before and it will still work great. I have bought some different magnets for it, mostly black/ metallic ones, but hope to buy colored magnets so that it is not as easily seen.
I enjoy the Lumo Lift posture coach as it has helped me maintain good posture each day!
There are not many verses about posture in the Bible, but there are some about standing up... ;-D
The Lord said to Joshua, “Stand up! What are you doing down on your face?
