The reference is not recommended. He stinks so by chemistry that I have washed him three times in the washing machine, to the terrible smell was gone. Cover is not put on your car seat. There is a small leaflet with bewildering comic pictures. Arrows and encirclements, so confusing, for 30 I had ene ordinary manual expected. In the tests, the reference to attach to the actual seat cover dissolves. Such a waste, I really would not have expected from Romans! We are now inferior to "Summer Cover" under a towel laid. This is inexpensive, does not smell, can attach itself and does not look worse than this terrycloth rag with rubber bands.
