Acebeam Rider RX

“I have a Rider RX, which I believe has the same UI. I have the same frustrations with it that you do. What I figured out was happening, in my case, was that the button was getting half-pressed all day long in my pocket as I sat down, crouched, kneeled, etc at work; like just the fabric of my pants bunching up near the button as I bent over was enough to press against the button and cause it to change modes. So despite having mode memory, I really could never have any expectation of what setting it would be at any time I clicked it on. Just maddening. That’s why, even though everyone out there recommends the Pokelit as such a great EDC light, I never bought one. I absolutely HATE the half-press click-through UI of these things.”
