I like them. It is bulky and hard to use but that can be a plus.
on more than one occasion before I carried the multi-unit I have
been working on a motorcycle or bicycle on the grass at dusk and
dropped the allen key that I was using only to have to fish for it while
the light got dimmer. If you drop an Alien there is no hide 'n seek
factor to contend with. Makes cleaning up easy too. Alien, flat
repair kit and a big fat crank hex will get me through any emergency.
