If there is anything to complain about, it is the very strong smell. in any case at the beginning (but is probably in all products of this type of case). I have the mats first washed in the bath properly and then added to the airing on the balcony. After a few days the smell had noticeably and is now barely noticeable.
The mats processed very well and meet 100% its purpose. I can only recommend it to everyone!
