I tried it before purchasing. The font, tick box selection and general feel is better, in my opinion, than that I have experienced with Adobe. My abilities are significantly challenged due to illness. The PDF document that I have to use presents with problems when I run it in other edit utilities. I may call on you if I get stuck, but so far I am favorably impressed with this product. Thanks. ;-)

Great Customer Service
I only needed the service for a specific period and thought I cancelled the service, until I was charged. I contacted customer service and gave every possible email address the service could be connected to, so I thought. None of those emails showed service connected to it, so they ended up submitting a trouble ticket. A few days later they contacted me to see if I was connected to another email address, and it was my husband's business, that I never thought about. Even though it automatically renewed, they responded that they would refund the charge.

For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Product reliability is verified by measurement. The metric for products that cannot be repaired, such as light bulbs, is mean time to failure (MTBF). The metric for products that can be repaired, such as digital computers, is mean time between failures (MTBF).
How do you know if a system is reliable?
If failure of any component does not depend on any other component, the reliability of the system is obtained simply as the product of the reliabilities of individual elements, R=R1×R2ÃR3Ã ARN=RJ.
What is the reliability of the system?
Reliability of a product is defined as the probability that the product will not fail throughout a prescribed operating period. The reliability of each component and the configuration of the system consisting of these components determines the system reliability (i.e., the reliability of the product).
How do you calculate reliability from failure rate?
If the MTBF is known, one can calculate the failure rate as the inverse of the MTBF. The formula for failure rate is: failure rate= 1/MTBF = R/T where R is the number of failures and T is total time. This tells us that the probability that any one particular device will survive to its calculated MTBF is only 36.8%.
Is MTBF a good measure of reliability?
Although useful to some degree, the mean life function (often denoted as “MTBF” or “MTBF”) is not a good measurement when used as the sole reliability metric.
What is a reliable product?
Definition of Reliability: Reliability is the probability that a product or equipment will perform satisfactorily for a given time under normal conditions of use. So reliability is related to quality, but it is something more than that.
What is reliability of a product?
1. Product Reliability is defined as the probability that a device will perform its required function, subjected to stated conditions, for a specific period of time. Product Reliability is quantified as MTBF (Mean Time Between Failures) for repairable product and MTBF (Mean Time To Failure) for non-repairable product.
What do you mean reliability?
reliability. The ability of an apparatus, machine, or system to consistently perform its intended or required function or mission, on demand and without degradation or failure. Often expressed as mean time between failures (MTBF) or reliability coefficient. Also called quality over time. See also availability.
