I have one. Yes it is High, Low, Strobe. No the strobe isn’t hidden. Next mode memory if turned back on within 5 seconds. After 5 seconds it just starts back in high. Beam and tint are nice. Same build quality as the A1. Can’t tail stand. Haven’t done a true run time test on it but it does last quite some time on low, which is what I usually use it on around the house. There are better AAA lights, the Zanflare F3 being one but, it is much smaller than the F3. In both length and diameter.
