It seemed to fit quite well. I put it on, put a dust bag on it and vacuumed it. I thought it was great! Then I tried to remove the trash can. I broke the handle on the dust bag trying to get it out. Finally there was someone pushing the trash can as I pulled it out. The dome is not centered. I didn't notice it during installation, but it's enough that I couldn't remove the dust box without using force. The return period has expired. If Qualtex sends me another one, I'll try again. If not, then we've all learned something.
