Owners of the Spandau S2 in 20 Gauge generally position it as an entry-level field gun that punches above its price tag for light upland hunting use. The 28-inch vented rib barrel and included choke set are frequently cited as legitimate value for a budget semi-auto.

The wood stock finish gets mixed reviews. Some owners appreciate the traditional look, but the factory finish is described as thin and requiring attention after a season in the field. Fit and finish elsewhere is considered adequate rather than refined.

Cycling reliability draws the most variation in feedback. Most owners report clean cycling with standard loads after a short break-in, but a handful note sensitivity to lighter target loads. The S2 does not attract a deep aftermarket, so owners who want upgrades typically move to a different platform.
