Has anyone tried these?

I was at Lowe's the other day and they had these on sale for 14 bucks. I was going to buy a fleece beanie anyway and thought what the heck and picked one up. I tried it out last night as it was 26 degrees. I was using the light to see my way back and forth from my shed to get wood for my firepit. I have to say I'm impressed with the warmth of this hat and it puts enough light out to see what I'm doing really well. I'm not sure how reliable the light would be but it would make a great backup on a winter trip where you would be wearing the beanie anyway.

If anyone owns one I would love to hear what you think about it and how its been working out for you.
