Comments on HMX x 80 Retros FJ400 switches | Comments on Aflion Blue Sky switches |
The switch color scheme is inspired by the Fuji 400 film roll. Compared to traditional HMX clicky switches, this switch has a more thocky sound. It features an HMX T2 material stem, P2 material bottom housing, and a PC material top housing that dampens the sound. With a total travel of 3.8mm, the sound is quieter compared to the 3.5mm travel switches – Deskhero. | The Aflion Blue Sky is part of Aflion's 2023 lineup and features a brand new mould that results in better quality and tolerances. Aflion is the manufacturer behind the Melody and Pink Robin as well as the Invokeys switches and is known for their amazing quality and sound. This switch comes factory lubed and therefore is ready to use out of the box. Their sound and feel is very similar to that of the Invokeys Matcha Latte – Beaverkeys. |
