What was for a while a terrible experience with this company was turned around by Customer Service Manager Paul Hughes out of the London office (even though I'm in the states). I ordered two wrong sizes for my computer monitors and no instructions stated to save the packaging in case returns were needed. I could not return or exchange the products because I couldn't find suitable packaging (it had to be large and flat). Around and around I went with emails. Everytime I called the USA office I got the London office who could never help. One employee emailed me and “proposed” that I “give away the screens to perhaps someone who could use it” in exchange for “ 50% refund.” This is absurd to propose that I wind up with no screens and half my money. Paul finally reached out and within days he had the correct size panels en route to me. (He asked for the models of my monitors to look up their sizes vs. the way their website suggests: measure by hand.) Paul saved the day. Thank you, Paul! The screens seem to be good. They dim the brightness for sure. As someone with Sjogren's Syndrome and eye issues, this helps me greatly.
