I can only talk about the Sebertech M2. I have owned it for 2 years and it has given good service. I use the screwdrivers often and they have held up well with virtually no damage. I used the pliers to turn my corroded battery terminals. They did well, no damage whatsoever.

It's a decent little tool for what it is. One caviat though. An idiot at the security terminal at the local INS office had to call his supervisor to look at the tiny thing and get a ruling on whether the tiny wire cutters were "edged weapons." I didn't have to surrender them.

In summary they are not my Leatherman, but for less than $15 they are usefull and more than a toy.
