MS series look nice and comfortable to use. All the heads & tailcaps are interchangeable in mechanical design.
Both the single AA and the CR123 look way too huge for their class though...
They are interesting, but they keep the same body for every type of battery, as a result we get a 1xAA light almost as big as a 18650 light (24mm diameter). More and more brands do that now, I guess to reduce the cost, but I don't like that.
Too bad it has no momentary and decent low. Seems like attaching a lanyard isn't as easy as it should be with these lights.
