Product review (3 stars): It does it's job
Sometimes it is hard to get a seal, but it does it's job once you get it in correctly. It does "explode" carbon everywhere when you unscrew it from the fridge so be prepared! I have not tried other brands so I don't have anything else to compare it to with this fridge. However, compared to other brands that I've used with non Lg Refrigerators, this would rate poorly.
