Product review (4 stars): Works but super-expensive for the material
The extender words just as it should.  However, I thought the other reviews were exaggerating with how flimsy and cheap the plastic is for the price.  they were so right!  The plastic is super-flimsy for that high of a price!.  Good news it that it's under our couch so it doesn't show.  But wow!  What a price for two pieces of plastic!
