Product review (5 stars): But once I pulled the dryer apart I discovered that all the rollers were just fine. I cleaned everything and reassembled the dryer
The roller appears to be high quality, but I didn't need it.  My LG dryer was making noises that made be believe I needed this.  But once I pulled the dryer apart I discovered that all the rollers were just fine.  I cleaned everything and reassembled the dryer, and it is back to being as quiet as when we originally bought it.  I've kept the roller in case I ever do need it.
