I made a purchase on their web site, asked that they call me and they did! Not only did they call me, the sales person made suggestions, changed the order and saved me money, getting me a mask that I wanted and saving me funds. The salesperson did not have to do it, but she did and I was thankful. This is uncommon in today's world, a business listens, changes and helps the customer while not trying to take advantage of them. This is a business that I'll always use. They have earned my trust and business.
