My experience exactly, my Olight i3E is always with me, battered and bruised though it is it still works perfectly.
I have recently ordered several candidates for replacement, including a S/S Tip, which may be too big, so far the only one to arrive is the S/S Convoy Tiny. Nice output and very solid, twisty switch that can’t come undone, but the threads are VERY rough and cannot be accessed.
