Excellent, trustworthy experiences over several years I've ordered several non-fiction books and several other products over 4-5 years. Disasterpreparer.com has provided excellent service and products in every case, and proven to be a trustworthy company that I can do business with at a distance. And they offer unique products to serve needs not fulfilled by other companies. I'm currently waiting on back-ordered devices not obtainable anywhere else, and experience has shown that I don't need to worry about payment in advance.

Beyond Comparison I have been buying products from Arthur Bradley and Disasterpreparer.com for several years. Every book, product, and resource he provides is well researched, tested, and of highest quality. The depth of his knowledge is incredible and is applied in such a way that the everyday layman can understand and benefit from it.

I recently purchased a quantity of… I recently purchased a quantity of ferrite cores, whole-house and broadband, from Disaster Preparer. The ferrites were quality made and fit my purpose precisely. Dr. Arthur Bradley, owner, really knows his stuff. He saved me a significant amount of time researching the ferrites with the correct attributes. The prices were very fair and shipping was expedited. One of the larger ferrites was damaged in shipping. Dr. Bradley replaced the ferrite within the matter of a couple days. I would definitely recommend purchasing from him.

What a breath of fresh air What a breath of fresh air. Opinion that is based on fact, sound theory, and actual test measurements!! I have been unable to find any other site that is always based on actual test data. Thank you Dr. Bradley for providing a rational, evidence based approach to the problem. (BTW, how can it be that such information is "classified" from government sources?)

Exemplary service Dr Badley: I can only say that ALL my business dealings with you have been nothing short of exemplary. All your products are top-notch, and all deliveries have been either 'on schedule' or early. That you have phenomenal credentials coupled with an ability to explain difficult subjects may be your greatest attribute. You are my most valued purveyor of both information and products for this critical subject.
