Nice review.
I actually like the full size Perun headband cradle over the velcro and clip retained Mini version, as it’s magnetized, and the elastic retaining strap is fast and easy to swap out lights, vs sliding thru H1R retaining loops. It fits the H1R, Perun Mini, and the Sofirn SP40 w/18350.
H1R in Perun cradle
Swapped to H1R band, for some matchy-matchy
SP40 in Perun cradle, diameter almost exact fit.
