Dear McGrath .... It works fine on Wild Flying Dove's home computer,but that's too big & heavy to cart around in a caravan ( trailer) at Folk Festivals,and only works on mains electricity !
       For the benefit of our American Cousins ; a "dongle" is a small "gizmo" that you can plug in to a USB socket on a portable computer, in order to access the internet ; most UK mobile 'phone networks have them available. So, if you're going away to a music festival for a week in your caravan (trailer),you can check your e-mails and stuff every day (if you must !!). Maybe we should ask for a refund, and buy a Virgin dongle instead ??
