It took my 20mm round bases and locked them into a perfectly rigid ranked formation with zero wobble. The MDF fits together cleanly, no sanding needed, and the models look much better for wargaming.

Samuel S. ★★★★★ Oct 21, 2026

I was pleasantly surprised how snugly my 20mm round bases fit into the upper frame—no wobbling at all. The MDF feels sturdy enough for regular game use, and the lower base keeps everything aligned in ranked formation.

The frame height options made it simple to match my existing bases perfectly, and the whole thing snapped together with zero wobble. My unit moves as one solid block now.
