Compared to the Samsung Trio 500, which I have been using for a week. The use of both is for switching between 3 devices: laptop, tablet, and desktop PC. The Samsung is smaller and has a better angle for typing, it has much more readable letters on the keys and a better feel when typing. Its downside is the lack of an LED for CAPS. The Keychron has more connection options, 2.4 dongle and cable, which are included in the package, and switching is done with a switch on the back. It has an LED for CAPS, very positive, and LEDs for battery and Bluetooth. Out of the box, the shortcuts on the F keys and when connected via Bluetooth to a tablet are strange, it opens a translator for example. All of this can be adjusted, and perhaps that is the essence of this keyboard. Many customizations, and huge convenience for those who need them. The 3* for ergonomics, completely flat and tiny letters on the keys. If you are looking for a wireless small keyboard to use with a Samsung tablet, go with your eyes closed for the Samsung Trio 500. If you want it for use with a desktop PC or laptop and you like/need customizations and shortcuts, the Keychron is quite decent at €30.

excellent keyboard, immediate response, no interruptions with a very nice feel when typing. I highly recommend it

Very convenient. The 2.4g connection is very good. So far there are no gaps or repetitions in typing. One issue with the Bluetooth connection, sometimes it "forgets" the connected device and you have to reconnect it. The issue with the down arrow that has been mentioned is true, however it works just fine.

If you are looking for a MacBook, just buy it. The layout is 1:1. I am a person who works a lot outside, on the couch, in cafes, etc., and I always had an issue switching between the laptop and the desktop keyboard. I finally solved this and can switch between the two blindly!

Very beautiful keyboard, essentially copying the design of the Logitech MX keys mini. From a company known for its mechanical keyboards. Silent keys, low profile, very pleasant typing feel and fast. It also has a US layout which means full shift keys, one-line height enter key, which is an important advantage for anyone who types a lot (especially the full shift keys).
Everything is perfect EXCEPT for one glaring disadvantage (due to which it loses a star): The up and down arrow keys are in the position of one key, separated horizontally, making them small (logical) but also not stable in feel! Especially the key for the down arrow from the very first moment gives the feeling that it tilts downwards and will lose its original position and remain tilted down! I hope this doesn’t happen, because otherwise it is an excellent keyboard! I got it along with the corresponding full-size one, which is also excellent, just for desktop, while this one here is much more compact so it’s easy to take anywhere...
If the down arrow doesn’t let us down, the keyboard is a bargain, especially at the price I got it (28.30€)
Personally, I recommend it, but with the caveat for the down arrow key (yes it’s so obvious and annoying that I say it again and again...)
EDIT: I return after a few days and unfortunately I will change my rating for the worse. The issue with the keys for the up and especially for the down arrow is simply unforgivable! And I don’t think it’s a defect of my keyboard, it’s clearly a manufacturing issue! What a shame, very shame, because I think the 14 days I can return it have passed... Everything else is fine, but not wanting to press the down arrow because your finger will slip and go down is simply unacceptable...
