Product review (3 stars): Don't be afraid to squish them
As they came they were about an inch too long and an inch too narrow. I trimmed one, then discovered that being sort of sponge-like I could squish them into place and they fit pretty good. Now that I know that I would buy them again. They do work, maybe not as good as the originals, but I really can't measure that. They are certainly better than old plugged ones and the price is good. I bought 2 sets to reduce shipping costs.
