I needed information concerning the manufactured date of "it's a 10" products to find out if they had expired. The number that I called was a recording stating to get in touch with the company by E-mail. I then E-mailed the company and received one response stating that the products have a one year shelf life. That response did not answer my question because I did not know when they were manufactured or when I purchased them. I have sent three E-mails since then, and I have not received a response back to answer my question. In my opinion, someone receiving my E-mails does not want to go through the process of finding the manufactured date on the products because it would take a few minutes of their time. I will not purchase any "it's a 10" products again due to a company that does not care about their customers' concerns.
