I've recently finished these as part of an ongoing project for a display game at the Colours Wargames show in September and wanted to share some thoughts.
Figures are 28mm, and roughly the same size and build of a Perry model. Detail is very nice, restrained but easy to paint still, and casting is for the most part superb.
Surprisingly, given the fidelty of the weapons, no breakages occurred, though I did managed to snap one of the running figures ankles, though this was my own fault and easily repaired.
This is all of the current Spectre range of Cartel models, but I'm most impressed, and look forwards to seeing more to come in the future all being well. Although a little pricey compared to other ranges, I feel the quality is worth it, and always enjoy these releases.
