According to two reviewers it is "flexible" and bends easily and the tire tools 'broke'. That suggests an emergency use only and a tool that can't be
expected to apply much torque. How useful a tire tool is depends on how easy your tire/rim combo is to R&R. Some basically don't need tools to
replace the tire and only a bit of pry to get the first bit of tire over the rim, others require 20-30 minutes of effort to do the same (eg my bent!!).
On the one occasion when an 8mm allen head crank bolt loosened up on a ride, an all in one tool was unable to apply enough torque to get me
more than a few miles.

My preferred tool kit is two of the ParkTL 1.2 tire tools, an MT1 wrench and the CT5 chain tool. It is reasonably light and versatile. I have only
needed the chain tool on three occasions over the past 10 yrs, but it is indispensable when needed. I also carry a few speed links for the chain
some tire patches and a never opened tube of glue, but since I also always have two spare tubes I have never used the patches. A few rectangles
of tyvek type polypro nonwoven paper 1" sq and 1x2" complete my rescue kit for the rare side wall rip in a tire. These are so tough they can
easily hold 60-80# pressure in a tube for rips in the sidewall-enough to get you home.
