Crowdfunding for JezailFunder’s new mechanical keyboard, the Jiffy75 (SP75), began on March 10, 2026, at 9:00 pm CST.
This model was highly notable even at the time of the review, and its main feature is that it uses a left-right split structure while adopting a relatively familiar row-staggered arrangement.
Jiffy75 (SP75) continues the design and wireless compatibility of its predecessor, Cornix, but is configured with more practicality in mind.
Although it is a split keyboard, it is easy to reduce the transition load from a standard keyboard, making it an easy unit to get into for users who are interested in a split keyboard, but are not comfortable with a special layout out of the blue.
It is also important to note that the keyboard has the appearance of an aluminum chassis with wooden accents, knobs, Tri-Mode connection support, and other elements that are required in recent years for a complete mechanical keyboard.
Greenkeys’ prior review of this model was also impressive for its ease of use and high build quality.
In addition to the woody maple x white/walnut x black coloring exhibited in TKX2025, the color lineup also includes “silver” and “orange” with the accent parts changed to acrylic material.
Super Advance Purchase starting at $199.00.
The split keyboard is a genre where learning costs are inevitably a concern, but the Jiffy75 (SP75) is one that lowers that hurdle a bit.
In particular, it uses a horizontal shift layout (row staggered layout) similar to a regular keyboard, so even first-time users of split keyboards will probably be able to use them with low switching costs.
The left-right split keyboard is especially recommended for creators.
KawamuraWe had a chance to talk to a creator who said that the left-right split keyboard is quite useful, especially for liquid tabs.
If you use a lot of shortcuts while also typing, this is ideal for minimizing arm movement.
Since it is not column-staggered and has a small number of keys like Cornix, the burden of thinking will remain the same and you will be able to get on with your work.
This would be a product to check out at the start of the program.
