Satechi Slim EX3 and Satechi Slim X3 are two wireless keyboards with a very similar style, but designed with slightly different users in mind. The EX3 is the more versatile model and more modern in terms of connectivity, while the X3 fits more strongly into the aesthetics and workflow typical of Apple users. At first glance the differences don’t seem big, but in everyday use it quickly becomes clear that these are two quite different approaches to the same hardware category.
Design and everyday use
Satechi Slim EX3
Slim EX3 is a full-size keyboard with an aluminum housing that feels more solid and more “desk-oriented.” It’s slightly larger and heavier, so it works better as a permanent part of a workstation than as a light accessory carried between devices. Its character is clearly utilitarian: it’s meant to be stable, comfortable, and ready for many hours of work, whether you’re using a Mac or Windows.

Slim X3 is also a full-size keyboard, but it has a slimmer and lighter form. Thanks to that, it looks more minimalist and is visually closer to Apple devices. In everyday use it feels more subtle and lightweight, so it may suit people who value simple design, a thin profile, and a more elegant presence of the keyboard on the desk.
Connectivity and compatibility

The biggest advantage of the EX3 is connectivity. The keyboard supports Bluetooth 5.3, lets you work with three devices wirelessly, and additionally with one via a USB-C 2.4 GHz receiver. This is a very practical solution for people who work on several computers or switch between Mac and Windows. An additional benefit is the system switch, which makes the EX3 simply more versatile and better prepared for mixed use.

Slim X3 uses Bluetooth 5.0 and also lets you switch between multiple devices, but its character is more “Apple-like” than universal. It’s a model that works best within the macOS, iPad, and iPhone ecosystem. It works on Windows, but it doesn’t offer the same freedom as the EX3, so for a user working across different systems it will simply be less flexible.
Backlighting and choosing a model

The EX3 focuses primarily on functionality, stability, and broad compatibility. It’s a keyboard for someone who treats it as a work tool and values more modern connectivity over visual extras. If the most important thing is convenient switching between devices and systems, the EX3 comes out better.

The X3, in turn, has an important advantage in the form of backlighting, which increases comfort when working after dark and in a dimly lit place. In practice, this feature may be decisive for many users. If someone works mainly on Apple devices and wants a slim, light, backlit keyboard, the X3 will simply be the more pleasant everyday choice.
Summary
Satechi Slim EX3 will be better for people who want a more versatile keyboard for Mac and Windows and care about more modern connectivity. Satechi Slim X3 will work better for an Apple user who prioritizes slimness, simple design, and backlit keys. In short: the EX3 wins on functionality, and the X3 on comfort and style.
