Common complaints
Large size and weight limits portability for everyday carryHigher brightness modes have shorter runtimePremium price point
No thermal regulation, causing step down due to heat after turbo mode.Threads are somewhat difficult to start or unscrew.Heats up significantly on turbo/high modes making prolonged handheld use uncomfortable.Limited retention options, some users find shoulder strap front mount flimsy.Low voltage protection is not fully clear; caution advised with unprotected cells.Large size and weight (over 600 grams without batteries) makes compact carry difficult.
