The smell is so strong that even after wiping it down it filled the room for a few days. Has started to dissipate but will leave points of contact with lingered odor. Apart from that, the product works very well. Shocked my PT didn't suggest me getting this sooner, as it's been the only thing to provide any type of relief to my upper back since a collision.UPDATE after 8 months: The smell eventually went away. Is going strong without any real signs of wear and tear, am quite surprised at how sturdy this thing is.
