fluid master 7500

Again I wanted to thank everyone who responded to my cry of help.
Now I need advice=my wife wants to do a lite bathroom redo and that means getting a toilet and cabinet and lights. cabinets and lights not a problem. the toilet is the problem has anyone a opion on the fluid master 7500 the waxless ring. it works on rubber o rings. the old wax ring keeps comming up thru the bolt down holes and makes a mess when cleaning . and again thanks...

If the inside of the drain pipe is clean, they work. I have a couple on my toilets. ANother brand that makes a similar product is from Fernco (I think).

If you use the Fluidmaster waxless seal, push it onto the bottom of the bowl first.
