You can't imagine how good this is.I'm not a relative or employee.
I wasn't sure if this was as good as advertised, when I recieved it I topped up the charge and used it.I was so amazed at how well it worked that I took it to my dental office for staff and patients to try it out.Everyone liked it so much that same day I ordered one for the office and expect it there tomorrow.Great price and effective.
