The Gram Spectrum was one of the new products Tesoro presented during Computex 2016. This keyboard comes with a low profile design and RGB backlight as well as new mechanical switches. The layout is quite simple and there are no additional macro or media keys, however, there are a few dual-function keys available, which has become a trend on gaming keyboards lately. This simple trick allows multimedia functions that can be used through an “Fn” button, which in this case has been placed next to the space bar.
The first impression the Gram Specturm leaves is very good, since it appears that the company is moving away from the flashy design towards clean and sophisticated lines. There is an aluminum faceplate carrying free standing mechanical switches. As we already mention this is a low-profile keyboard including RGB backlight. Thanks to the fact, that the switches are free-standing makes the illumination clearly visible. The keycaps are made using the the so called double shot injection process, which means that the legend is not printed but injected with differently colored plastic. In this case the legend is transparent, which allows the backlight to illuminate it. Typing on the mechanical switches Tesoro Agile switches (Kailh Red) feels linear and predictable. The key-travel measures 3mm but actuation happens after pressing the switch down by 1.5mm. Tesoro had the Agile mechanical switches made solely for this keyboard. Compared to other switches the body of the Tesoro Agile is transparent which allows for clearer lighting. The Agile switches are available in different colors and types and the manufacturer promises an endurance of guaranteed 60 million keystrokes.
On paper this all sounds great but what about in daily usage? We used the Gram Spectrum for a whole week and we liked it very much. We are aware that comfort in the case of keyboard is, at least to a certain extent, down to personal peripheral. However, thanks to the low-profile design there is no need for a wrist rest for instance. The only aspect that puzzled us is the font used on this product; in our opinion it is too "gaming oriented" and we believe a less flashy font would have opened up an even broader target audience.
The back of this keyboard isn't particularly special. There is the usual label showing the serial of the product and there are four rubber feet - one in each corner. Obviously there are two small feet, also with rubber ends, which allow for tilting the keyboard to a certain angle.
