PFD has tested many products in extreme climate conditions. This has given great focus and separated talk from action, marketing from reality. Being cheap, can be very expensive. However, this does not mean that it needs to be expensive, but it does need to be reliable and produce consistently repeatable results. PFD has done much of this analysis and knows what works and what is just marketing hype. The value proposition for PFD is one of Quality, Reliability and Affordability.
