Great light! This is a second one I purchased as an extra or backup because I never want to be without one of these lights. I purchased about 6 of the fixed lens head lamps for myself and friends, but this one is far better. The zoom feature is great and has no bright spot in the center field of view like the fixed lens models have. The amount of daylight no longer dictates my outdoor activities. When the sun goes down, I put on my headlamp and keep going. Last night I finished mowing my lawn in total darkness with this light. I will be ordering more to give as gifts to friends and family.
We live in an area where too many times the electricity goes out so have begun to use head lamps more so than flashlights since with the headlamps, they free up both of your hands to be doing other things. Also, being waterproof, they have been used out in the rain as well or very misty air. Even though we still have and use regular flashlights, having these headlamps have been a huge help for many hours of use!
I am a Veterinary surgeon and I have found this to be the best light for surgery I've ever purchased. Most surgical headlamps cost several hundred dollars and don't have the illumination, comfort and design features that this light has. I'm going to buy more as gifts for my colleagues. An outstanding product with prompt service and personal attention from this seller. Bright, white light - rechargeable batteries - AC, car and USB chargers included. unbelievable!!!
