Product review (5 stars): Perfect Fit!
I had noticed for a couple of months that lint was getting coming out of the outside vent at my home. It turned out that the lint filter assembly on my LG Dryer was not working properly. The felt rim seal near the bottom edge of the assembly had come loose and was allowing lint to get past. This is a potential safety issue because lint in a dryer vent can cause a fire.

I should have acted as soon as I saw the lint forming at the dryer vent outlet outside my home, but for some reason I ignored it. Fortunately I figured out what was causing the problem and was able to purchase a replacement trap from Amazon.

I had to clean the dryer vent outlet completely since there was lint in the vent from the dryer to the outside vent area.

The replacement fit perfectly.

I am concerned since I have read many online posts of the felt rim seal failing and allowing lint to bypass the trap. I do not know yet if this replacement will suffer the same problem. However, the original lasted about 5 years before if failed. Based on the appearance of this replacement, I expect this to last a similiar amount of time, and I will be watching the outdoor vent exhaust for evidence of failure.
