Review on Logitech Backlit Programmable Certified Refurbished by Michal Adach ᠌

The first six buttons on the side should be set to F1, F2, F3, Ctrl-F1, Ctrl-F2, and F3. Everything, with the exception of the F1 button, was allocated work. The button or profile replacement was ineffective. The lowest button beneath the scroll is in the same circumstance. The Alt function in any of the profiles was rejected by the button, but other functions were accepted with a boom. When I hung the Ctrl function on the G-shift button, it ceased to function further. All of this was tested on three separate PCs. The same applies everywhere. It's possible that I'm doing something incorrectly, but it appears to be a software bug more often.
