Fantastic product & service
i bought this map book as a back up to google maps. sometimes when out of range it will be handy to see what our road options and distances are..being older my eye sight is not as good as it used to be and some of the fine detail is a little hard to read.the layout is good with each state clearly given a section for quick reference.even though the book doesn't update over the years the main roads ,towns and distances would only change a small amount so should be good to have around for years of travelling.
quick service good product fits and works well
Perfect as described extra toilet cassette for our van, great service I ordered the wrong one first time and easily rectified thanks
