Well, there has been a few reviews of the gun. One was of a pre production model review by a Dutchman who found all sorts of things he thought were wrong with the gun. Many of those bad points were later shown not to be true. There are also some very positive reviews from happy owners across the big pond. I have no hands on experience but the gun is simple and seems to work well while providing very good accuracy with it's CZ barrel. Biggest issues seem to be stiff cocking that gets easier with some use and a whining regulator. The shroud is also rather loud. Personally I'd choose one over the Impact due to price, simple construction and traditional rifled barrel + no reported QC issues in production guns.
