INTRODUCTION

   Although pretty much everything in the PC industry changes rapidly thanks to advancements in technology the keyboard and mouse combo are the only two things that have remained pretty much the same since the beginning. Sure we've witnessed the introduction of new and improved membrane and mechanical switches, extra features like macro keys and backlit illumination and different tracking technologies such as optical, laser and LED but in the end the shape and basic functionality of both remains the same. That being said mechanical gaming keyboards have become very popular especially amongst serious gamers, enthusiasts and professionals not only because of the increased durability (up to 60 million keystrokes) and feedback (both audible and tactile) offered by mechanical switches (always compared to regular membrane models) but also because of their features including the newly introduced RGB key illumination. Not long ago Tesoro introduced the Excalibur RGB Mechanical Gaming Keyboard and since it got a really warm welcome by gamers all over the world it didn't take long for them to update it by launching the Excalibur Spectrum Mechanical Gaming Keyboard model which we'll be looking at today.

   Established in 2011, Tesoro Technology USA Inc. is a team of multinational gaming enthusiasts with over 30 years industry experience with one objective – make ultra-durable products that give the best gaming experience. To achieve this, Tesoro conceptualizes products from the input and feedback from the gaming community, and then builds them using the highest grade components. As a gamers company, Tesoro continues to expand into new horizons and push the limit further with each product unveiling.

   Just like the Excalibur RGB model the Excalibur Spectrum is quite small since it follows the standard 104-key keyboard design without any sort of bells and whistles so unlike the larger (and better looking for some) Lobera models it may not appeal the same way to gamers. Under its hood Tesoro has placed a 32bit ARM Cortex Processor with 512K of built-in memory (supports up to 5 gaming profiles) and has once again used Kailh blue/brown/black/red mechanical switches with gold plated contacts (60 million keystrokes) which feature full RGB color illumination (16.8m colors). The RGB backlighting feature includes 7 different illumination modes (trigger/ripple/fireworks/radiation/breathing/wave/spectrum), 4 different brightness levels and can also be used individually with any of the keys (or not at all). The Excalibur Spectrum Mechanical Gaming Keyboard also features 6-Key/N-Key Rollover, 1000Hz polling rate, 6 multimedia keys, double injection keycaps and instant macro recording.
