Familiarity: I've put it through the wringer
I really like these lights: low cost, lightweight, great light beam, easy to operate along with a flexible/rotating "head". OK, I confess battery changes were always met with anxiety as the latch does seem "fragile". I can see how others thought the same thing. I just watched the PTEC marketing video on the lamp. Now "who would of "thunk" the headband adjuster was designed to assist opening the battery lid!!! It works great! Shazam and Goolllly! My anxiety is now gone! I always thought this was a good lamp, now I say great lamp. If you want to waste you money and carry more weight, yeah, go ahead and buy a more expensive and heavier BD or other lamp!
