I use and Advantage but have not tried the 360.

How do you find it?

Have you used the older models to give a comparison?

I have two advantage 1s and two advantage twos. All are modified with either the blue-wizard board or the tint (or predecessor) boards as well as other mods (sound dampening, switch swaps). All but the blue-wizard runs QMK. I've been using this line of keyboards for over 20 years at this point.

The 360 is quite nice with a few caveats.

1) the split is excellent, the extra buttons are great.

2) the backlight is kinda pointless, I have it off, why waste the battery. I don't understand why they didn't put it in the non-pro... BOM price i'd guess.

3) I got the palm rests, they are comfortable and kinda a little leatherette material so they won't get gooped up as badly as the old advantage 2 cloth pads.

4) the keycaps that come with it are SHIT. Buy the PBT caps with it, or do like i did and buy them two days after you get your keyboard.. Even the the home row is shit if you are used the adv1/2. I took the homerow off of one of my original advantages and put it on the pro. You might be able to swap all the caps over, but there are a few extra keys on the 360 series that it won't cover, and some of the legends will be wrong.

5) The adjustable tenting is nice but somewhat limited, it has essentially three settings.

6) It certainly sounds better, not the hollow of the adv1/2 (which i stuffed with foam to suppress).

7) You might want to buy from upgrade keyboards unless you are ok with browns. I haven't opened it up to see how hard it would be to do a desolder/switch swap. Brown are ok for me, but I do enjoy my adv2 with silent reds.

I have several KA2s (office, home office, spare) and the 360 Pro (I first had a non-Pro because I prefer wired, but the firmware still had annoying bugs).

+ Variable split is very nice.

+ Higher tenting degrees than the 20 degrees of the KA2.

+ Great firmware (ZMK) out of the box.

+ Really good build quality.

+ User-replaceable battery.

- The Gateron Brown switches are mediocre. They are not to spec and the actuation points are closer to 3mm than 2mm. This makes it much harder to type without bottoming out and doesn't permit the lighter touch you can use with the Browns or Silent Reds in the KA2.

- The two halves always connect through Bluetooth, but sometimes the right half cannot find the left half, especially after flashing. You usually have to power cycle both halves several times to get them to connect again.

- The Pro (in contrast to the non-Pro 360) comes with mediocre ABS keycaps. I replaced them by a Kinesis PBT blank set, but this adds another $50 or so to the already steep price.

- The optional palm rests are too high.

- Cannot be used on your lap.

The keyboard I still love the most is the Kinesis Advantage2 with a KinT controller (for QMK). If the split distance and tenting degree of the KA2 are acceptable, I'd recommend people to buy the KA2. If you do get a 360, I'd recommend you to go through Upgradekeyboards.com and get it with a different switch type.

Yeah If I buy a second 360pro for the office i'm going to buy it from upgrade keyboards so i can get silent reds or some other switch.

I also replaced the keycaps with the pbt ones, but i also moved a homerow from an adv1 onto my 360pro.

Yeah, I also replaced the caps and would like to get some PBT spherical caps from signature plastics.

It's a bit sad that they switched from Cherry to budget Gateron switches (on a 600 Euro keyboard). The Cherry Browns and Silent Reds may have been a bit scratchy, but at least they are always close to spec and not that bad after some break-in. Either that or one of the literally tens of tactile switches that are better than Gateron Browns, e.g. why not put some Boba U4 or U4Ts in a premium keyboard? Sure, these switches are some smaller runs, but I am sure they could have worked something out, Kinesis got Cherry to invent Browns after all.

I think replacing the non homerow caps is a bit unwise. They have weird profiles that are not simply row profiles. However I really like the spherical DSA deepdishes they used to put on the homerow. So I use the ones from one of my spare classic advantages.

I also bought the 360 and I love it! Haven't once thought about going back to the Kinesis Advantage I was using before it. I went with the wired / non-pro version since I've had too many bluetooth issues with peripherals to trust that it wasn't going to be an issue. Sure enough, I asked on the subreddit and some others have reported connection issues or flakiness.

The only issue I've had with it is that sometimes my laptop doesn't receive any input so I have to unplug the keyboard and plug it back in. This could just be due to my setup and unrelated to the keyboard, but I didn't have that issue before.

The magnetic snap-on wrist pads are really nice. They snap perfectly into place and haven't moved unless I want them to. The keyboard overall feels solid and ergonomic

On occasion I have issues with the left half right half pairing and have to reset it. I have yet to dig into the code to see if I could resolve a bug yet. (left half runs as a 'central' and is paired to the machine, right half pairs to the left half)
