I often pull this out in my shop, which is funny since i have all the full size tools i need there. There is something great about being able to switch from tool to tool so quickly, not to mention not having to find the right tool to begin with. I have even installed new chains removed old chains with this multi tool. And being able to take all that on the road...as Visa says, priceless. it takes a wicked beating as well. Only drawback is keeping tools not needed folded while operating the one you do need.
First, the selection of tools is fine. It has everything I need (short of a chain tool) for my rides. However, the tools themselves are connected to a bar at their base. That bar, if you look closely at the picture, is fastened to the rest of the tool which screws. These screws can come loose just by riding. Imagine you're out in the middle of nowhere and need to make some adjustment. Now imagine going into your bike bag and finding your multi-tool in pieces because the screw has come completely un-screwed. Not so fun. Poor design.
