Product review (4 stars): So far this seems to be MUCH better than the original Lint screen on my dryer.
When I first got this screen I worried that it was such a tight fit.  After calling the company and reading some other folks answers, I am sure that this isn't going to be a problem.  The screen is pretty tight, but it's doing a great job.  Only time will tell if it will last longer than the original.  It boggles the mind that SO MANY people have the same issues with this lint screen and Whirlpool is apparently ignoring it!!
For me, this seems like just the right thing to buy and good value for the money!  If your Whirlpool dryer filter is falling apart (as so many have done), try this replacement.
