Although I dont need any more dongles (have enough spare ones), out of curiocity I ordered it last week.
As the stock at Amazon has finished, I had to order it directly from Radarbox24. Lost the advantage of Amazon Prime, had to pay $4.99 shipping in addition to $9.95 price. Two weeks delivery period by Royal Mail. Still waiting delivery.
