Basically it is a tyre inflator and deflator in the one unit which allows you todo 2 tyres at once. I won't say too much more about it as Ronny does a pretty good job of that in his review. Well I got onto Ricus the guy making them in South Africa and well it turned up today



Gotta say I love this thing, it's a tad on the costly side with the freight from SA but there is now a Aussie reseller but as they aren't a forum sponsor I better not mention them. When you however combine the cost of an ARB rapid deflator and the ARB inflator the price seems pretty reasonable to me for the benefits.
Really well made, good quality and over all very very impressed with it. Glad I took the punt after watching Ronny's video.
