The worst $400 you’ll ever spend. Had this placed under my sectional couch (which does not sit directly on top of the rug) for a total of 3 months. Regularly vacuumed, wasn’t even in direct sunlight and moved our couch to move and it’s completely discoloured in one away. No spills, no accidents and would lift the couch to vacuum not fully move the couch so never noticed before. Also not in a high traffic area, so I just don’t get how this could happened. Tried to contact customer service and their solution was to place the discoloured part under the couch again and give 10% off a future purchase. Completely ridiculous and frustrating.
