SK05 or Wuben X4 — Which flashlight should I choose for long-term use?

Hi everyone,

I’m trying to decide between the SK05 and the Wuben X4. The SK05 costs about twice as much as the X4, so I’m wondering if it’s worth the extra money for long-term use.

I really like the design of both lights, but my main priority is durability and reliability over time — something that will last with minimal issues. I don’t want frequent small problems or replacements.

For people who have used either (or both) — which one would you recommend for long-term everyday carry and why? Any thoughts on build quality, reliability, service, or durability would be greatly appreciated.

Thanks in advance!
