Having this on the trail has come in handy a few times, but it got rattled apart in my saddle bag. Easy fix, but still inconvenient timing.
I carry this guy in my saddle bag. It's light enough and has everything I need to make roadside adjustments. It's small enough that it fits tightly into my saddle bag.
Good for what it is
It's a mini-multi-tool. It works well enough for what it is. It's a pain to use sometimes, especially if you really need to torque a bolt or fit through a tight space. On the other hand, it's lightweight and compact and easy to fit in the smallest of saddle bags. It's well constructed and tough. Tool selection is decent, most of what you'll need.
I stopped carrying it while mountain biking because I discovered the hard way in a race that sometimes you just need a chain tool on the trail. Still fine for road biking, though.
