Query: Did not work at all!!!

I was so disappointed in this product after such great reviews! I needed something to block out my husbands window rattling snoring! These did nothing in that regard. Also, they were so difficult to handle. The cotton left a mess on my hands and the plugs were greasy. Too bad. I was excited about these working. I ordered Flent contours instead. Lucky, I was able to return to Amazon for a full refund. This is the biggest reason I shop Amazon!
