I bought a Stormforce cover for my Porsche Boxster from CoverYourCar.co.uk in Nov 2019. It fitted very well and, I thought, was a good quality cover; I was pleased with it. HOWEVER, just like many of the other reviews here, the top layer started to disintegrate after about two years of occasional, short-term use through Spring to Autumn (the car goes into storage for the winter months). I took the matter up with CoverYourCar earlier this year but got a very unsatisfactory and unhelpful response: the warranty had expired and that was all there was to it. Although they also volunteered UV damage as the cause and stated... "Like any fabric left outdoors, it will degrade over time" This is clearly at odds with the marketing blurb on the website which states: "100% Ultra Ultraviolet Resistant fabric..." So, be warned, these Stormforce covers are not fit for purpose after only a short period of use outdoors. By contrast, I must say that I also have a Voyager car cover from the same company which fits equally very well and, after 12 months, seems to be more durable and is more resistant to UV, having a silver finish, (albeit of a thinner and less breathable fabric) - time will tell... fingers crossed.
