I own this flashlight, and I like it. I believe I purchased mine directly from Sofirn.
My main critique is that while the **build quality is very good, it results in significant weight.** If I could change one thing, I would suggest using a lighter, more fragile material, as items strapped to a head typically do not require such extreme durability. This change would necessitate better heat dissipation, likely through additional cooling fins, a trade-off I would accept.
My first light was the HS41, which uses a larger battery and is heavier. Wearing it on my hard hat all night resulted in noticeable strain from the weight. This model mitigates that issue by utilizing a slightly smaller battery.
It would be an excellent enhancement if it featured separate **rotational knobs** for both brightness and light selection. Outside of that, I appreciate the design. Ideally, the existing switches would be dedicated solely to power and programmable presets.
Regarding thermals, I think there should be a small **air gap behind the LED** instead of using the entire flashlight body as the primary heat sink, but I understand these are all design trade-offs.
If I had to grab one light to go out, say, trick-or-treating, I'd put this in my pocket. It provided the necessary light whenever we needed to address the fact that the costume my three-year-old was wearing kept causing her to trip.
Lastly I should mention I've only used the hands-free sensor one time trying it out. I find the feature a waste of space, the rest of the light is fine.

edit:
tried on the light to consider this comment further, and I have to say it might be a little bit heavy to run. it's a little heavier than I remember. it's still right there on the edge where if you used the head strap perfectly and you were willing to tighten it a bit, you can manage, but I think there should be a better one for running. it's just got enough aluminum that is kind of Hefty.
I love how it uses a standard 18650 which is very long battery life and can be replaced when battery dies.
In for another one, this one looks like is brighter
