Did not meet stated expectation
No, I do not recommend this product
Battery life did not match manufacturer specifications. At full brightness with both the front facing flood and spot turned on, battery life was only 1hr and 16 minutes. This is much less than the stated 4 hours. Additionally the brightness was not constant and kept on dimming, prompting me to continuously increase the brightness. Will try the Biolamp 800 which has a constant brightness setting.

Not reliable
No, I do not recommend this product
Quality seems to be good. But when I arrived on site and needed it bad - it didn't even start to do what it was intended to; only short flash after any button press, battery was 100%.

Good comfort, poor battery life and lifespan
No, I do not recommend this product
After a few months, battery life went way down. Starts blinking low battery alarm after only a few minutes. Also, you can't wash the headband.

Loved it... for a short while.
No, I do not recommend this product
Like others have said, battery life fails. The features are great and it's comfortable. It just doesn't last.

Failed on the trail
No, I do not recommend this product
Worked intermittently, I was on a trek in Peru and the head lamp failed, now it doesn't work at all. Even after being charged, only the red light blinks when the switch is pressed!

Failed first time the lamp was tilted
No, I do not recommend this product
I like the overall design and light it gives, but the power button worked only intermittently after the first time I tilted it down to direct the light. It’s a design issue because to tilt the lamp, you have to push forward away from you on the power button which puts force on the button in an unnatural direction.
