This is a great basic tool kit and provides the minimum that each person will need to carry for glacier travel. Keep in mind it is the basic minimum and supplementing it with another pulley, an ascender or 2nd tibloc, and a couple Petzl OK oval biners would round it out more fully for most situations. Easy way to store and grab on the go to have the minimum when heading out into crevasse land. Just be sure to take a couple snow anchors and a couple ice anchors along and your set. A 2nd tibloc would put this at 5 stars, but you can add that pretty inexpensively. Most of all buy it and practice using it before heading onto glaciers.
