I bought this for bicycle shop work on shocks, derailleurs, and other items with small or tough-to-see parts.  While the clamp, light, extension range, and cord are all good, the magnification is not so good.  It allows me to not wear my reader glasses, but it isn't that powerful and the clarity of the lens leaves something to be desired.  Overall, it's a good addition, but I think this one will be making it into my daughters' art closet, and I will search for a better option for professional application.
