Repositionable
First and foremost, a loose toilet will often cause a wax ring to lose its seal and leak.
Next, in the event that you have to replace your toilet, your wax ring will lose its seal, so you'll need to install a new one along with your new toilet.
With Toilet O-Ring, this won't occur, you can use the seal as many times you need.
Toilet can be removed and reinstalled with the same seal attached.
