Product review (5 stars): As described and delivered when scheduled
Was 2nd time ordering.  Order 2 years worth at a time.  This time I was short as I discovered after the trash ran.  Was going to wait the 10 business days but then the really cold snap came in.  Went to HOme depot and got the sets (upstairs and downstairs) I needed.  And glad I did.  They ran hard to keep 42 %.  The  ones I ordered work well again.  I fitted a set up to check.  Now I am set for 2 1/2 yrs  Very happy to get much less than Home Depot.
