I purchased this map for a week-long trip spanning across Yucatan, Mexico. I had used a map by this publisher for the DR with great results.
The laminated material holds up quite well to repeated opening and folding (and misfolding), as well as rain and other accidents frequent when road-tripping.
All of the major routes are well marked, as well as a lot of minor ones. While it's often easy to find maps of cities within tour books, maps that span the entire state *and* provide sufficient detail are very rare. This map is a necessity if you plan to drive around the state.
Gas stations are marked well, as in rural areas, there may only be one every hundred miles or so. Even small routes narrow and with livestock running free were marked on the map. When we took a wrong turn, we were thankful to have this map to send us on the right track via a secondary road.
The blow-ups of cities are also a great feature, again because tour-book maps often have the centers of cities only while this map included the surrounding areas.
The only note is that the spellings of some cities varied from the ones on the road signs, but that was a minor point.
