When I saw this item, I thought to myself, “Wow, something that might be better than those icky wax rings,” so I tried it. I ended up being surprisingly happy with it! It comes with the option to install it for two different heights (no more wondering if you need regular or extra thick), the wax did not create any goop, I felt more confident doing the new toilet installation knowing that if I needed to re-position it, the ring wouldn’t be wasted, and it came with clear instructions. The toilet has been in use for several months and works great. I will only buy these from now on instead of the old, gooey kind.
