What adventurer doesn't use rope? Very few; and that's what makes this booklet a nice idea. Moreover, it's well presented, and worth the low asking price.
The book covers various different types of rope, pointing out that, for most adventurers, the rope in the standard equipment list is probably heavier than they actually need. There's discussion of the block and tackle (an item on the standard equipment list that's never really explained), and of rope bridges, among other items of equipment, as well as a basic discussion of the use of knots. All handy, simple information, well presented.
Some useful magic items too - and good to see that the Box of Infinite Rope is priced high enough to make it difficult to make a profit out of the thing (and thus put ropemakers out of business!)
I have a few minor quibbles, but nothing serious. There are a few typos here and there, and a few oddities in the layout, but nothing that causes a problem. I'd have liked to see a little more on rope bridges, and it's unclear why rope made from the silk of giant spiders is weaker than that made (presumably) by silkworms. You'd have thought it would be stronger - the strands must be thicker, right?
On the whole, a good, basic product, well-packaged for the price.
