Another toilet flange question

Hey all,

Has anyone used or heard anything positive/negative about the toilet flanges that fit INSIDE of a stack? This would save me some work in my basement but heard cases of it being prone to plugging?

Thanks to all you fine people!

They are not prone to plugging----

However----the 3" inside flanges have a small opening and often cause installation problems---if it is mounted on top of the finished floor--sometimes the toilets drain horn will hit the inside of the flange,causing the toilet to bottom out and rock---

If you do use one---make sure the flange is flush to the finished floor.

I've had trouble with these several times and will not use them.
