This Review Title is Blocks Stinks and the content is: Love these! I bought them for work but have ended up using that at home more. They work really good as long as you remember to breathe through your nose and not your mouth! I have reused the same pair a few times with no issue. I have recommended these to lots of nurses/cnas at my work and I am so glad I found them. The only hiccup was shipping. It gave me a delivery date very far out. They showed up pretty quick compared to the estimated date. But they still show in my Amazon that they haven’t arrived. I am glad they came quicker!.There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
