Great lamps, reasonable price
April 27, 2010

We had first bought chintzy little headlamps from Target, but after they both broke within a year, we realized immediately we needed to stop cheaping out. Still, hiking gear can add up pretty quickly so we didn't want to buy really expensive ones. This headlamp is the perfect compromise, has good light modes and a good quality strap. Would definitely recommend.

Great no frills headlamp

I was down to the bottom of my budget for my latest trip and needed a new headlamp. I wanted to spend more, but after purchasing this headlamp, I wonder why. Very light, very reliable, rugged, nice two beam pattern. After my one week trip I'm still on the original batteries! Great value, great product!

great buy

These headlamps arrived in two days with free shipping. We already own two of these headlamps and have had no problems with them. The LED's seem to last forever. They make great gifts!

This thing is junk! The high mode stopped working a month after i received it.

Great headlamp for the price!!

WOW this baby is bright...the setting for spotlight mode is really great when you need a solid beam of light while the other setting using the two LEDS is great for using around the camp. Not sure how long the batteries last since I have not used it that much.
