I work for a large tradeshow/exhibit house, and we spec'd an LED diffuser product from W4S, they didn't have enough in stock for the large project I was working on but James managed to, by some miracle, get a full roll of the diffuser material shipped from Barcelona, Spain to our Las Vegas facility in a matter of just a few days. He stayed in constant contact with me, and the carrier all the way from the time we clicked order, until the project was complete. Absolutely stellar customer service, and excellent quality products every single time. I cannot recommend this company enough. Thanks W4S!!!!
