Product review (1 stars): Waste of money (not the product... this listing).
This may actually be a wonderful product at a great price, but how is one to know from the listing.  Are we to believe that EACH of these insulators is $45!  I doubt it, but that is what the listing says.  Are we to believe that this item will fit any size steel t-post?  Frankly, it APPEARS too small to fit any size t-post.  What a waste of money to post an item that is so poorly described and ambiguously priced.

I give the product 5 big question marks.  The person writing the product listing gets an F.
