"72 year old fingers CANNOT open the battery compartment. My husband ripped his thumb nail bed trying to pry it open. I couldn’t budge it. I will never buy Black Diamond again. I am considering returning it. These batteries better last 10 years because I can’t open the compartment to change them."
"Single button is terrible and there's no red lens :("
"Easy to operate and excellent illumination of dark trails and spaces! I highly recommend!"
"I’m trying to install batteries - no instructions and the video does not mention - I’ll be returning this to rei"
"It is very frustrating trying to put in the batteries. More information about this would be useful!"
"Simple and affordable. Perfect."
"I cannot even figure out how to open this to put in batteries! No clear directions online or by the QR code provided. I now have to drive back to REI and ask for help from a real person."
"Light is nice and bright, headband comfy and snug…only problem is that I need to replace batteries every single time I use it. It doesn’t matter if I use it for 20 minutes or 2 hours. The batteries must be draining even when light is off. The battery compartment is super difficult to open, making it an even bigger issue."
"Not only did the battery clip stop holding the battery in after 2 months, the time I spent to register the product on the Black Diamond website on day of purchase meant nothing because they wouldn’t honor the warranty without my original paper receipt. Cheap and not worth it."
"There are no instructions for installing the battery"
