Tesoro GRAM Spectrum RGB Gaming Keyboard Review

Closer Look at the Tesoro GRAM Spectrum RGB Mechanical Keyboard »

IMG_9282Mechanical keyboards have been around longer than most people think and they are in fact quite common in vintage PCs. They have become less popular through the years as mass production favored low-cost membrane keyboards but mechanical keyboards have regained popularity once again when gamers and typing enthusiasts sought something more tactile and precise. Currently, there are many options available such as those manufactured by Cherry, ALPS or Topre, providing a variety of tactility and actuation to meet finicky keyboard enthusiasts. Cherry’s MX switch series is the most popular mechanical switch type currently used, but manufacturers such as Kaihua also offer an alternative Kailh switch using the same Cherry MX mounting standard; a solution that has been used by gaming peripheral brand Tesoro with many of their keyboard offerings.

For their latest GRAM Spectrum RGB gaming keyboard, Tesoro has tapped Kaihua to make a new “Agile” switch series that has a lower actuation point and shorter total travel time compared to the regular Kailh switches cloned after Cherry MX solutions. This is essentially Kailh’s answer to Cherry’s latest MX silver switches. The Tesoro GRAM Spectrum RGB is available in either black or white versions and have fully-customizable per-key RGB LED backlight. For gamers, the Tesoro GRAM Spectrum RGB offers NKRO via USB with the ability to switch to regular 6KRO for compatibility. There is a live macro recording function as well with multiple profile storage banks for different game settings.

Tesoro’s packaging is simple yet effective. What I like to see is a maximum amount of information at the back and I think Tesoro has that nailed down with GRAM’s box. Even before opening up the packaging, it is very clear what is inside the box. In the front and back, there are numerous snippets that show pretty much all signature features of GRAM. Inside, the keyboard itself ships in a plastic bag to avoid any miscellaneous scratches while being securely held by couple of foam fillers on each side. The accessories are housed on the compartment above the keyboard.

There aren’t many accessories included here, in fact, there are none at all with the exception of the detachable USB A Male to USB Mini B cable and quick start guide.
