The first impression is positive. The perceived by many customers chemical odors I can not understand at all. The product smells when removing from the packaging, although minimal for plastic, but only slightly, and that the whole bathroom could stink afterwards, I find completely absurd. If the knobs were somewhat smaller, perhaps the anti-slip effect would be even better if, but overall met the mat its purpose. Could be a bit bigger in my opinion. Optical so embellished a mat the bathtub, of course not, but I think about it you can favor a safer entry and disembarking ignore.
