I don't want no hunk of glass, electronics, batteries, and wires bolted on top of my shotgun to slow me down, add weight, and have to baby around in the brush. And yes, I have done some training with e-sights of various types and do not care for them on a shotgun. If I absolutely had to have one for the one or two valid reasons requiring one, I think I'd look hard at the new Burris Speed Bead. Otherwise, bead and rib, twin beads, fiber optic bead, ghost ring aperture, or iron sights all work so well I have no use for anything else.
