That machine looks very good and certainly has the features. I have no experience with the unit at all. If it does what it says it does, it would be a good all-purpose machine. It is not a true dual-dielectric machine since the anode, like the Synergy and Maxi is made from stainless steel. A true dual-dielectric machine has no metals in the gas stream.
The price on the unit is very good, especially since it comes with tubing, a diffuser and a pediatric regulator.
