Hello Gary,
I did of course re-read your 2021 ultralight shootout.
My incarnation of the R-108 seems better then the one you reviewed there, and the ones in your 7.5 inch R-108 slider video. They seem to have cured the strange noises etc,. The Amber back-light is much easier on the retina than the 1000 lumens white searchlight that my D-808 has :). The Sihuadon R-108 doesn't seem to have the numerous dead carriers that the XHDATA D-808 has either.
The black colour makes the white and orange labels easier to read than on the grey version. Ironically the black version was £2 cheaper than the grey version on Amazon UK.
