Product review (5 stars): very satisfied
I got the product in just a couple days.  My dryer was making a fair amount of squeaking noise while the tumbler was in motion.  I had already taken apart my dryer to clean it (there was a ton of lint inside).  After doing my research, I figured the roller wheels were just not spinning freely, so I tried polishing the spindles.  After putting it back together, the noise had decreased some, but not enough for my liking.  I then ordered this product after learning my dryer came from the factory with just a belt tensioner "pad" and not the wheel (factory cost cutting?).  I also felt the new rollers would be quieter.  I took everything apart again and was able to install fairly quickly for a non-dryer-tech (1-2 hours).  The wheel tensioner was definitely more difficult to work with than the pad, mostly b/c it is simply bigger.  Getting the belt back on the motor took a little more time/patience, but the dryer is back to being "factory quiet".  The vendor was prompt with my order and included all the expected components & instructions.  I would order from them again.
