Product review (5 stars): It installed  great and worked well for about 6 months  AND STILL WORKING
It installed  great and worked well for about 6 months - now I hear the tell-tale noises indicating it will need replacing within another 6 months.  Given the price, I am okay with it.  It did lead me to clean out dryer - which was an unknown fire waiting to happen.  I filled my vacuum thrice cleaning the lint and debris.  Not mention i found 3 socks 6 dollars and a hand towel.  :-)
If you're on a budget buy this one - If not, get a better quality one from a known manufacturer.
UPDATE: Update from 3- 5 stars. Package still works fine,  the issue I attributed to poor quality was the symptom of the dryer's drum, felt going bad.  Once it was replace we are back to my dryer running smoothly and quietly!
