The headlamp is amazing but that's not a surprise it's super bright it's got good battery life but which stayed out was the customer service that replaced my headlamp with out any hassle when the 1st one burnt out and I received my new 1 in less than a week.... I will definitely cosign for the authenticity of their customer service and warranty any day
It's got three settings: bright, brighter, and light of God. I use it continuously during my 10+ hour workday then leave it on the charger until the next day. It's comfortable and lightweight. I highly recommend this headlamp.
I am a surgeon and I use this to do procedures in the office. It works great. I only use the brightest setting when the battery has lost some power. I have also used it on home construction projects. I got the extra battery and am never out of power. The power switch is little difficult sometimes. It can be wiped with alcohol, so it is useful with the Wuhan Virus issues we are dealing with.
