Product review (4 stars): I like it!
I was a bit worried at first because this is NOT an OEM (made by Whirlpool) product. It is scary to use something non-OEM on something that could be dangerous (cause a fire)... but like other reviewers, I have had my Duet pair for 7 years and the felt started to fall off after a few years and I would just pop it back in place and hope for the best.
This one doesn't have felt like the other one and you have to really give it effort for the first few weeks of using it to get used to that. I still see lint behind it and under it despite the good tight fit when I pull it out...so if you clean yours out with a trap brush or vacuum it out you will still feel the need to with this one.
Overall, I am happy with the purchase.
I gave it 4 stars because of the lint I still see around it inside the dryer inside the trap opening...but the construction is excellent!
