I ordered this from Amazon about 2 months ago. It has been working well - seems to last about 4-5 hours on a charge while using the lamp on the front. A bit longer without it. It is VERY bright - I can see it reflecting off of surfaces when I am within an arm's length or so. The first time putting it on was a little confusing, but once I figured it out it wasn't a big deal. For $25, I definitely recommend it.
