I got a set at cost from a local HS as a friend that works there highly recommended them. For close work they provide excellent magnification and unparalleled clarity...but I find them awkward as they must be flipped up to return to normal viewing. I find myself preferring my half lens readers where I can look down for magnification and up for normal. If I were a figure painter I would probably use them more.
I took the plunge and ordered a set. I used the survey discount code Tamiya USA is offering now. 25% off was good enough for me!
