Introduction

We took a look at Tesoro's flagship Gram Spectrum RGB keyboard earlier this year, which heralded a lot of things that made it an attractive package - from the low-profile keycaps to the Tesoro Agile switch. The latter was a collaboration between Tesoro and Kailh to compete with the Cherry MX Speed (Silver) switch, and since then, Kailh has gone ahead and put up more such switches themselves. Tesoro decided they liked the idea of collaborating with mechanical switch makers, and this time they worked with Gateron on making some optical switches instead. Enter the Excalibur SE Spectrum, and thanks again to Tesoro for providing a review sample for us today.


The Excalibur SE Spectrum is not a replacement or update to the Gram Spectrum, of which we will have a similar version with optical switches coming up as well. Instead, this is Tesoro's product aiming at the $100 price point and looking to get optical switches more popular in the enthusiast keyboard market. To be clear, optical switches are not new to the market, and we examined one from Bloody before on TPU too, but the market has less players with optical-switch products today than fingers on my hands, so there is definitely a thick pie to go around. So let us begin our review with the specifications table below.
