The Good: Slim and compact, reliable, contains all essential tools.
The Bad: Chain tool is uncomfortably small. Prone to rusting. 8mm hex key is not very useful.Overall Review: I've been using this tool for trail repairs and even occasional garage work for four years without any serious problems. It fits easily in a jersey pocket or saddlebag. It includes various sizes of hex keys, a T25 torx key, flat and Philips screwdrivers, a chain tool, and spoke wrenches.I haven't had a problem with any of the bits rounding.The hex keys are great, although the 8mm seems unnecessary because the tool is too short to provide the kind of leverage needed with most 8mm hex bolts. The flat screwdriver could probably be eliminated too. The chain tool is short, so it's difficult to grip, but it does work and has saved multiple rides from turning into hikes. The tool has picked up some spots of surface rust over the years, but it's still working just fine. I never go on a ride without it.
