I took a chance buying at a distance, of a brand I don't see in stores around a me with no way to feel the product and test it's suitability. I bought it at the start of October and despite the messages about them moving warehouse and possible delays, my new keyboard arrived within 9 days of dispatch no damage, customs didn't break it, there was no additional costs from customs either (review the UK customs website to understand what value that kicks in at - approx £130). The keyboard itself is heavy in a sturdy way, the switches are great, keycaps feel a little thin/cheap, but I'll customise those and overall very happy with my purchase! Thanks Keychain, love the keyboard!!
So I'm writing this review as someone who hasn't tested every key type, switch and material known to humankind. It's cool there are so many options for people to chose from when it comes to mechs, I suppose that's what makes them so alluring. This is my first foray and no doubt that has an impact on my opinion of this keyboard.
And I love this keyboard! Personally I'm glad I gave it a try despite some of the brutal one star reviews.
Prior to this, I have been using primarily the keyboard on my late generation MacBook Pro. A good keyboard, I still enjoy it, but it's not nearly as enjoyable as using the Keychron. it's super easy to setup with the Mac as well, both with usb and bluetooth, works straight out of the box. And I really appreciate the function keys defaulting to support screen brightness, volume, etc
If there is a negative, it is probably the height of they keys from the desk. it's a high setup. I typically type without resting my wrists on the desk however so perhaps it doesn't affect me as much as it might others.
If you're on the fence definitely give it a try.
Recently bought this keyboard after always using whatever cheap thing came with the device. I must say I do love it and feel pretty extra af. The issue is, and it's the only issue I've had thus far, is with the labeling of the switches to toggle between Bluetooth, Win/Mac. The letters are black and very small. So they blend into the black case so it's very hard for me to read. Maybe on the next version make the a bit larger with a white stamp/overlay so it's a bit easier for folks with eye issues.
Overall I like the feel of the keyboard and think it has good construction. I was looking for a wireless keyboard that had brown switches to replace my Das Keyboard w/ Blue Cherry. I only use this keyboard for work which it does a great job, but can’t speak to it’s gaming abilities. The price point was nice and don’t feel I overpaid.
I have had no issues with the Bluetooth connection. There is a power save mode so it will disconnect intermittently throughout the day, but quickly re-connects. The battery lasts about 10 work days, which is less than I would like, but is fairly easy to recharge with the usb-c connector. The battery life is mostly likely due to my usage of the keyboard LEDs. There are quite a few built in light programs built in, they cycle using a key in the top right of the keyboard.
Because of the compact size there are a couple of areas that I am finding myself relearning while typing. The zero key on the 10-key is smaller because the up-arrow key takes up the area that once comprised of half the zero key. This takes getting used to when I use the 10-key. Also finding the arrow keys while typing, without looking is still a struggle. On a full size keyboard they are by themselves and I can find them easily.
The biggest complaint I have is with the height of the keyboard. I would say it is about 7mm higher than my Das Keyboad. Which doesn’t sound like a lot, but it did give the sort of negative feel to the keyboard at first. Because the height is higher than normal keyboards a regular wrist pad still isn’t flush with the keyboard. I had to have a friend create a wedge with his 3D printer to make the wrist pad flush. I did not purchase the Keychron wrist pad, I purchased a wooden wrist pad off amazon. I don’t know if the wrist pad for keychron is a different height.
The Gatreon Brown switches feel real good and I am very happy with them. I have not used Cherry Browns, but was told my someone who does that they feel very similar.
I still enjoy the keyboard and will not be returning it, but if Keychron was to release a keyboard resolving the height I would be sure to purchase it.
I just received this keyboard to use on my Macbook pro and my Windows Desktop. I'll connect it to my phone when I get a chance, but thought I'd get something out for folks quickly.
1) It has more click / noise than the brown switches. Honestly this is what I wanted, not too loud. The browns were basically none. Pro for me.
2) The keyboard is high. Much higher than my other non battery keyboard. Not sure if that will be a challenge, but I use a wrist rest anyway, so not a huge deal.
3) The documentation isn't good. Really in our outsourced environment when is it. To pair multiple computers you have to hold down the Function key and the number key (not F1...). So, Function + 1 will be the first device. Pairing the second for me required that I hold Function +2 for the second device to pair. The documentation says hold Function + 1 to pair which I tried, but basically I just paired into slot one. Not complicated, just don't believe the manual.
4) The keycaps come off easy enough, but I tried pulling the switch itself and honestly thought I might have damaged the switch, and it still didn't come off.
5) You can use bluetooth with the keyboard plugged in. I'm doing that now. If you turn it off it will connect to the last device, but only after you push a key. Just like my mouse.
