Printed on very strong (plastified?) paper it should last a long time. It is reasonably detailed for the scale of the map of 1:850 000 (1 inch to 13.4 miles or 1cm to 8.5 kms) The island, which is long and narrow is split into two halves, one on either side of the paper without much overlap. This could make using it in a car a little awkward. The key is clear, but it could have been repeated on the reverse side for easier reference (see use in car re- turning over), there is plenty of sea area. An index of placenames is provided but "A" to the middle of "L" is on one side and from "L" to "Z" on the reverse. Some little niggles in an otherwise very good map for your money.
