Exile Steel Cage with Internal Lock

Has anyone here used the Exile steel confinement cage with an internal lock?

I'm not sure which specific model you're referring to, but I own several of the ones they advertise and purchased them all for under half price—sometimes significantly less. Other products in that line also seem overpriced. Check out Lock the Cock, DH gate, Amazon, or eBay; you'll find identical units at much lower prices there. It appears these companies aren't manufacturing the cages themselves but are simply selling off-the-shelf (OTC) versions for a premium. For custom options, take a look at Badass Works. I'm really pleased with the one I ordered from their CUSTOM section. Just my humble opinion. Mikel
