Our funeral home has been a customer since 2004. We had previously used time-release spray systems that were expensive to operate and very difficult to maintain (my responsibility to take care of). Almost every person that walks through our door comments on the product and it seems to be just as strong at the end of the month as at the first. There is a great selection of fragrances and they know what I like and always have good recommendations on what I should try. I recently suggested adding an additional unit to our facility next time, and they had everything with them to do it on the spot. I would recommend Nature Scent products and services to anyone whether for their home or business.
