Tesoro has a very attractive, minimalistic keyboard with the Gram Spectrum. Gram Award Skills Posted on May 17, 2017 ← So I liked the Tesoro GRAM Spectrum very much. The flatter design, after all it is about 1.5 cm flatter than a normal mechanical keyboard (for example, the Cherry MX-Board 6.0), makes itself felt when typing. With the Tesoro Gram Spectrum you get in any case a high-quality keyboard to the hand, which does not put on excessive functionality. It depends more on good haptics and great writing. So you float with the hands above the keys. Also while gaming you will not be disappointed. →
