I use several flashlight of this type as ship surveyor and can say that the newer version be lower quality -lrb- make in china -rrb- than before . con : 1 . this flashlight be big and very heavy 2 . the battery last about 2 hour 3 . the switch be not so strong 4 . can not charge a spare battery on original charger 5 . if you hit the flashlight you burn the bulb the power adapter fail after one month . pro : 1 . focus ability 2 . good light
