This thing is awesome! I've already used it to pump up my tires (tested it out while replacing a tube, and then pumped up two other bikes while out on a group ride), it 'just worked'. Only thing I'd complain about is it didn't have the one size of allen key I needed for the bolt on my seat, but it does fine for the derailleurs, shifters, brakes, and everything else I've needed to do in the last week. My only complaint is maybe the tyre levers are a bit short - when fitting the new tube on this wheel, I was having to keep using the tools, and worried about snapping them, where I would usually shove a tool in and use strength and leverage to just slide it along the rim pulling the tyre out. But in a pinch, these are FINE!
