great
Only played around with this at home because it's august.. but so much better than the classic roll-up design from petal, bd etc. Fits more screws, screws actually stay in the ***** bag and don't come out inside a rucksack to spread your other gear. Fits full rack of 12+ screws. Kind of pricey, but not that bad because it replaces 2-3 conventional ***** cases, plus works so much better.
