How do I know when I should charge this deep tissue massage gun?
The body massager has an LED battery indicator, if only one LED is left on, please charge it in time to prevent the machine…
Is it easy to massage your own upper back/shoulders with this or would you need a second person to use for this area?
You should probably have a second person.
Can I use this massage gun to give massage on my neck and foot?
Yes it works very well on neck and foot.. Love it on the neck specially!
