I had the UV-21R version, looks identical. Had the dark background. I like the display with the large numbers and the number pad being more "normal" with 0 at the bottom.
However, the display went out after 1 week. Returned it for replacement. The replacement had white back ground, which is the older firmware and the white back ground was harder to see and it had smaller numbers in the display. I returned.
Bummer because I like the 999 channels and upload and download to Chirp was way faster than my other Baofengs.
