Beadlock Questions

Anyone ever use these or have any idea if there are any downsides? Looks like a great alternative to expensive beadlocks

"No more popped beads, DOT or balance worries. Staun beadlocks securely lock both beads to the rim by dividing the tires air chamber into two parts. Through a separate valve stem, the bead lock is inflated to 50 psi. Have you ever had a tire bead problem at 50 psi? Through a second valve stem, you can literally set your tires to any pressure you want. If the tire goes completely flat, you still have what we call a "limp flat" capability; the bead lock is a cushion between road and rim allowing you to drive back to camp or a more convenient spot to change the tire.

I want them for the sand. Its not needed but with 10 psi and 50+mph then add a turn its a good idea
