Introduction

After a couple years on the ErgoDox EZ, I’ve switched to the Kinesis Advantage360. The transition was smoother than I expected, but there are some meaningful differences worth covering.

The switch

If you’re coming from an ErgoDox, the Advantage360 layout will feel immediately familiar. The key positions are close enough that I was typing at a reasonable speed within a day or two. The big adjustment is the key wells. The ErgoDox is a flat board, so your fingers move across a plane. The Advantage360 has concave key wells where each column sits at a slightly different depth. It took about a week before my fingers stopped hesitating on the edges of the wells, but once you adjust it does feel more natural. Your fingers travel less distance and there’s less lateral movement, which is the whole point.

Key wells

The sculpted key wells are the main selling point of the Advantage360 over flat split boards. After a few months of use, I’d say they deliver on the promise. My hands feel more relaxed at the end of the day compared to the ErgoDox. The curved layout follows the natural arc of your fingers, so you’re not stretching or curling as much to reach keys. It’s a subtle difference, but it adds up over long sessions.

Wired vs. Pro

Kinesis makes two versions: the Advantage360 (wired) and the Advantage360 Pro (wireless with ZMK firmware). I went with the wired version and I’m happy with that choice. The Pro uses Bluetooth to sync the two halves, and I’ve heard enough reports of connectivity issues and input lag to steer me away. I also didn’t want to deal with charging batteries. The wired version uses a cable between the halves and a USB connection to the computer. It just works, and that’s what I want from a keyboard.

The trade-off is firmware. The Pro runs ZMK which is open source and very customizable. The wired version uses Kinesis’s SmartSet programming, which is more limited. For my layout it’s been fine, but if you rely on complex macros or layers, the Pro might be worth the wireless hassle.

Tenting

The Advantage360 has built-in tenting, which tilts each half so your hands rest at an angle rather than flat on the desk. This was something I had to jury-rig on the ErgoDox with aftermarket stands, so having it integrated is great. The tenting angle is adjustable and I’ve settled on somewhere around 20 degrees. It makes a noticeable difference for wrist comfort, especially combined with the key wells.

Other differences from the ErgoDox

Build quality. The Advantage360 feels more solid than the ErgoDox EZ. The case is heavier, the keys feel more stable, and there’s less flex in the board. It doesn’t slide around on the desk.

Thumb clusters. The thumb cluster layout is different and, in my opinion, better. The ErgoDox has a lot of thumb keys but several of them are hard to reach without moving your hand. The Advantage360 has fewer thumb keys but they’re all in comfortable positions.

Hot-swap switches. The wired version doesn’t support hot-swap, which is a downgrade from the ErgoDox EZ. If you like experimenting with different switches, keep this in mind. I had my holy pandas from the ErgoDox and was happy to stick with them, so I had Kinesis install those at build time.

Portability. The ErgoDox is slimmer and easier to throw in a bag. The Advantage360 with its key wells is bulkier. Not a dealbreaker for me since my keyboard lives on my desk, but worth mentioning if you travel with yours.

Conclusion

The Advantage360 is a solid upgrade from the ErgoDox if you’re looking for better ergonomics. The key wells and integrated tenting make a real difference for comfort. The transition is easy if you’re already used to a split layout. I’d recommend the wired version unless you specifically need wireless, and even then, check the current state of the Bluetooth issues before committing.
