Many enthusiasts probably haven’t heard of Tesoro Technology, which is perhaps understandable, since the company is so secretive their web page doesn’t even have an “About Us” section. Apparently based in Milpitas, California, Tesoro started out making mechanical keyboards a few years ago and has since branched out into mice and headsets, all aimed at gamers. Benchmark Reviews has just received their latest product, the RGB-illuminated and programmable Excalibur Spectrum mechanical gaming keyboard, so let’s take a look at it!


Although it’s rather generic looking, the Excalibur Spectrum supports a wide range of lighting functions as well as a robust macro capability.


  • Seven backlighting modes, plus per-key color adjustability
  • Individual mechanical key switches with 60 million key stroke durability
  • 512K of built-in memory supporting 5 gaming profiles
  • N-key rollover
  • 1,000-Hz polling rate
  • Choice of Kailh blue, brown, or red switches

Let’s take a look at this keyboard in the next section.
