Here's the one I have.

I like the HF model because it has the flip-up and rotate-up lenses
for a total of 4 discrete magnification possibilities. I just used it
tonight to help pick out some pine bark splinters I got while playing
around a lady's porch. I was all itchy and prickly when I went over
to prime a patio cover frame.

After a long week and longer day (10 hours of painting in up to 89F
sun today), I'm ready for a nice, cool, relaxed, do-nothing weekend.
