Product review (5 stars): MUST USE HAIR DRYER !!!
Worked perfectly for my 3 year old Whirlpool french door stainless fridge.  I can't stress this enough:  I highly recommend everyone to use a hair dryer and defrost the back inside portion of the fridge until it dries up completely.  I made the mistake of installing this piece and hoping it would fix the problem.  2 days later it started leaking again (sheet of ice forming at the bottom) so I had to open it back up and start defrosting the back area within the freezer with a hairdryer.  I must have sat there for a good 20 minutes blow drying until the flow of water from the melting ice stopped completely.  I also poked the drain where I install this extension piece with a chop stick (I'm Asian) to make sure all the ice was gone.

It's been a few weeks since I've seen the skating rink at the bottom of the freezer and I don't see 1 single drop of anything.  Sold our house recently and will be moving out in a month so these buyers better damn well appreciate my efforts (would've felt guilty leaving the fridge the way it was...).  Not buying a Whirlpool for our next house that's for sure.  FYI: Paid $14.
