Judging by the tube sight, it's the same guy who was on some of the forums years ago trying to convince us it was a good idea. lol Same type of guy who comes up with products you see online all the time and think "Why though?" You see it for sale and think "interesting idea, but did you really think that would sell? You admire their ingenuity. Admire their thinking outside the box, and how they stuck to it for years to see their dream realized and finally get produced.
You also feel bad for them, knowing their dream is dying on the vine, that all their time, effort and possibly life savings are gone. You also think.. are you an idiot?
That's also the reason you don't want to shoot single action revolvers with a partially loaded cylinder, higher pressure big boomers in particular. Even without the contraption, with the right (wrong) combination of things you can get enough pressure back through that chamber to bend the loading gate.

That phenomenon actually happens A LOT with black powder revolvers, and in my years of fixing and tuning them, have seen it more than a few times. Very rare in the .36 calibers but in .45s with large powder capacities like the 1847 and 1848 Walkers and Dragoons and the Remington New Model Army's, which can deliver ballistic performance on par with moderate to hot .357 Magnum factory loads. If the ignition cone vents are new and not corroded/worn out, they are not a problem even with 35+ grain powder charges. But with cones that have been fired so much that the vent channels are much larger than they should be, blowback and considerable outgassing occurs at the rear of the chambers also and sometimes the force is enough to blast the hammer back to full cock. Had at least one case of a Uberti made 1848 Dragoon with worn out cones that did that and went full auto on the shooter. A four round burst happened before the alarmed shooter almost dropped the gun. Once the factory cones are replaced with chrome lined Track of the Wolf cones, the issue stopped. On all my currently in use percussion revolvers, including my 1851 Colt and 1863 Remington Navy models, I use SlixShot cones that angle the cap ignition jet outward into the chamber like a showerhead for consistent firing and these have always been reliable in both ignition of the charges and elimination of rear outgassing that causes velocity drops at the muzzle end. I tell all new shooters of black powder revolvers that they should immediately replace the stock cones on new handguns with Track of the Wolf or Slixshot cones. These are made from much harder steel alloys than the factory ones. The stock cones are often called "reenactor" model cones, and for the exact reason: They are meant to be fired with blank loads for historical reenactments. If you want the best performance when using the guns for hunting, defense, or target shooting, you have to upgrade the cones.
