Common complaints
Heavier and larger size due to high capacity batteryBeam distance reduced compared to previous model due to wider beamBattery capacity exceeds 100Wh making air travel complicated
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.
