Thank you very much for making it clear this uses a very flimsy rubber tail button. I prefer a metal button, but some manufacturers make a sturdy plastic or metal button that just uses rubber to cover the end. Acebeam does this with some of their lights. This one is a no go because it is the flimsy rubber button covering that tears easily.
Unfortunately, they cannot create a system that remembers the strobe mode. So you can turn on the strobe with the back button. So far, I have only encountered this possibility in the case of Andruil 2, i.e. you can turn on the tactical mode to activate the last mode. I saw that they have two tail switches, but in my opinion this is not a convenient solution, especially when wearing gloves and when quick access is needed.
A nice package for most people, and regarding the quality - I've used my Sofirn SP40 headlamp daily for nearly 5 years and it still works perfectly! It only cost about $20 on Sale - I feel like I owe them some more money lol! Nice review, thanks.
