content: I have recently been exploring SUNGAZING and I wanted to be responsible regarding the care of my eyes. This monitor is exceedingly user friendly regarding UV readings with the added plus of giving an estimated time for being safe in the sun light. I also use the time function as I have recently dispensed with wearing a watch on my wrist. I'm interested in temperature as well but only in a casual way. The monitor is a bit slow in terms of adjusting for the temperature, but this might be a good thing in that so many things seem to be moving so fast here in 2011. My primary interest is in acquiring a quick(four seconds) read on UV light and this small unit fits the bill perfectly.
