I had an older generation Spot from some years ago. I found it very useable and just upgraded to the new one. The two buttons are an improvement, although I find them a little stiff compared to my old one, maybe they just need a bit more use. I like the tap on the side feature, but it took me awhile to get it to work. I was tapping too hard and brief. It’s more of a touch than a tap. I noticed the new beam right away. It is a lot brighter and I think a bit more focused than on the old one I had. Regarding how long it runs, I’ve never used it in a situation where I needed a lot of run time. Being able to set the output level to the most comfortable amount and to have red available have been important. I have also pocketed it some times, although it’s a bit big for that with the head band. I haven’t noticed PWM, but haven’t gone looking for it either.
Reviews for the Storm have never been as good as the Spot. I think the extra colors are inconvenient, unless you really need them all.
I also have a Sofirn D25S which I like quite a bit, but it doesn’t have red or ramping. I’m tempted to try modding it with Anduril.
