Purchasing Used R10

Hi All, first time question from new member

Has anyone any experience of buying a second hand R10? 

I expect that no E6connect courses will come with the unit as they will have been registered to the previous owners E6 licences,

Will the unit itself be free to be connected to the Gamin golf app in my name.

Im thinking that the money saved on purchase will fund a membership to GS pro ThumbsupThumbsup
