2nd time purchase
I have used this sprayer for more than 2 years for storing colloidal silver.  I put it in my bag all the times.  In case anyone around me coughing or sneezing,  I spray once to each of my nostrils to prevent germs and viruses from getting into my respiratory system.  The sprayer is durable and convenient. I purchased the sprayers again and gave them out as gifts.
