I have no complaints about the 2500 itself; a fine light and holds a decent charge; but that absurd harness for mounting the light one one's hand, was s hard-no. For over three hundred dollars on sale, that set-up -- hobbling the use of one hand, really needs work.
I ended up having to buy an L & M ball-mount, which oddly enough, actually had a place for a lanyard.
What will they think of next?
