I bought this light to clamp onto my embroidery hoop, and it is everything I wanted it to be!  I use it to help me be able to see the stitches I'm making better when I'm working in places where the light leaves a lot to be desired. It has two light settings, which allows me to get the supplemental light I need.  And it's flexible, so I can position it to reach exactly where I need it.  Plus, because of flexible neck, it folds up rather small and fits nicely in my embroidery bag.  I've only had it for about a month, and don't use it every day, so I can't comment on how long it will last, but I'm happy for now!  Also, the seller contacted me about a month after the purchase to make sure I was happy, which I thought was nice.  They really seem to care that I'm a happy customer.
