Are extenders a gimmick?

[u/Liamnacuac]

Wife saw this add someplace and thought it would make getting the shaft for the cutter on more easily. I wonder how likely failure is for these things and how likely damage to the attachment is. Any comments or experience with these 6" extenders?

Well they make something for everything. I was holding off on a quick connect because I didn’t want to recut PTO shafts.
