Excellent service, prompt delivery. I bought a piece of Ferroflex to use when I facilitate events at venues with non-magnetic whiteboards. Works perfectly. It stuck to the whiteboard very firmly and our magnets stuck to the new bight, shiny white surface really well. Would also be an excellent product to renovate an old whiteboard rather than replacing it. Removing the plastic backing sheet took a lot of work - 2 people pulling hard - so a warning about this would have been helpful, but we got there. I have replaced the backing sheet and re-rolled the half sheet I will carry to venues so I truly hope it will be easier to un-stick next time. (We mistakenly rolled it onto itself for the trip home - another 2 person effort to unroll it.) Great service, great product. (Suggest a few more details in the description.)
