75% with an OLED screen and knob
The Satisfaction 75 is an exploded 75% keyboard manufactured by CannonKeys. The 75% layout is a more compact alternative to the more common tenkeyless (TKL) layout. Like the TKL layout, the 75% layout features the arrow keys and function row, but arranges the keys in a more space-efficient manner. What makes this an "exploded" layout is the spread between the arrow keys, function row, right-most column, and the remaining keys, resembling an "explosion" of these parts. This results in a layout that is slightly less compact, but greatly less cluttered.
The mounting style of the Satisfaction 75 is known as a "sandwich" mount. This mounting style involves the plate of the keyboard being "sandwiched" between the top and bottom halves of the keyboard's housing, or case. This mounting style is a bit outdated by today's standards, offering a stiffer typing experience as opposed to the flexibility of more modern keyboards.
The Satisfaction 75 is inspired by the "Satisfaction" pirate ship owned by Captain Henry Morgan during the 17th century. This pirate theme can be seen in the packaging for the keyboard as well as its brass weight, which has an engraving of an anchor, cutlass, and treasure chest.
The stock PCB of the Satisfaction 75 is requires soldering the switches, OLED screen, and ALPS encoder. The PCB has been made "hotswappable" by soldering 3305 Mill-Max sockets in each of the switch sockets. This allows for switches to be installed and uninstalled by simply inserting the switches into the PCB as opposed to soldering and desoldering them.
The OLED screen on the Satisfaction 75 can be programmed to display various images. By default, the PCB is flashed with a screen that serves as a dashboard, displaying the time, date, and indicating whether certain keys are active, such as caps lock.
The display that I am currently using on the Satisfaction 75 displays the time, typing speed, and an image of a "bongo cat" that moves according to how fast the keys are pressed. The firmware for this display was created by Reddit user 'pedker' and the source code can be found here.
The PE foam is a thin sheet that is placed between the top of the PCB and the bottom of the switches. This foam modifies the sound of each keypress to be higher pitched, which might not be preferable by all users. I found that the sound of the PE foam is desirable, but can be too loud at times. The case foam is a thicker sheet that is placed below the PCB and dampens the resonance from the aluminum case, but heavily reduces the flexibility of the keyboard. Since this keyboard uses a sandwich mount, there is already minimal flexibility, making the consequences of case foam negligible.
The Satisfaction 75 is a keyboard that packs many features into a compact form factor. The keyboard also features a low front height of 17mm, reducing the wrist strain. These features make this keyboard a great option for long-term use and productivity. However, the stiff typing experience due to the sandwich mount might not be suitable for everyone.
