Brilliant Aussie deal

Been buying Ultra gear for years and this is one of their better ones. The Ultra 6.4 quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.
