Taking lots of vitamin C and resting, my husband is doing better today. He has the PW3 & now the PW4. Side by side the PW4 looks a little whiter. Also I compared the PW4 with my Voyage and the Voyage looks a little brighter. I think they have a coating on the PW4 that makes it look a little different. He did put both PW3 & PW4 to the brightest setting 24 and then they looked the same. Only when he adjusted to his reading setting of 12 they look different. Not by much though.
