It works for a sm

I have had one of these on my straw for about a week and the mold growth is concerning. I have never had mold in my straw before using these but now I realize these create the perfect atmosphere for mold to grow. Wet moisture is being trapped in the straw. I gave it a 3 stars because I do like the product, but you’ll have to clean it every day to be safe and I don’t think that’s worth it. Little air holes (small enough so spiders cannot crawl in- because that’s my fear) would be a better design IMO.
