This keyboard is perfect for those who want hardcore gaming or generally pvp and fps games. The only sure thing is that it’s not for games where you talk a lot in chat because it’s a 60%. It also makes a very good, strong clicky sound. I’ll mention some shortcuts so you don’t have to look for them... fn+Ctrl changes color, it has many colors, fn+alt changes the mode, and to switch from the F keys (f1, f2...) to the numbers you have to press fn+1.

It is a good mechanical keyboard for its price (€25) with a relatively long cable, nice sound on the keys, and RGB. I just can't understand the logic behind making the fn button a toggle and not a hold button. In short, if you want to press F1 for example, you first have to press FN+1, then press 1 for the F1 command to execute, and then press FN+1 again for the 1 key to work as "1" again, whereas they could have simply made it work as F1 with two fewer steps by just holding FN+1. Okay, it's a matter of habit, but literally, it's not user-friendly and makes its use unnecessarily difficult.

the keyboard is very convenient due to its size, especially for someone who has a setup with limited space. Its keys are particularly soft and not as noisy as my previous keyboard (ck108) with blue switches. In short, the keyboard is worth its money from every aspect and is convenient if someone needs something handy.

The CK61 is one of those small, mini keyboards that make you say, "wow, this is going to be a tool!" — and indeed, it wins you over visually. RGB lighting that makes you feel like you're playing inside a nightclub, sturdy construction, nice sound on the keys… overall, it makes you want to type even… a shopping list. Its cable? Wonderful. A little premium feeling.

BUT.
Here's the but in capital letters.

Because it's 60%, you have to know by heart a whole… grammar of combinations. Want arrows? You press Fn + I-don't-know-what. Want something somewhere else? Another hidden command. Want to change the lighting? Another sequence. At some point, you don't know if you're writing a message or entering a cheat code in GTA.

If you have an elephant's memory or you like mini keyboards, you'll love it. If you just want to work and play without also playing Sudoku with the keys, a classic full-size solution is better.

All good after almost a year and a half, to be honest I haven't used it yet for hardcore gaming because I stopped and lost interest, but even for the work it has done for 30 euros, it seems more than enough to me. Very good quality for its price. I just don't like that there isn't software like Razer

The switches break immediately!! Beautiful and affordable but that's it.
I do not recommend it to anyone. ( I also got the ck108 ) and it has exactly the same problem!

Very beautiful and impressive due to the lighting under the keys. It's just quite small, I would say child-sized

It's really good the switches sound amazing, the delay on the switches are unoticeable, the fact that it comes with a puller really feels like you bought an expensive keyboard, it took me 5 days to understand the 60% keyboard concept but now i find it convenient i recommend you buying it

Very good for the money, except for the fact that the battery broke after 1 year and I replaced it, 3-4 keys that don't work, the BT that has a delay, the metallic sound it makes when you press the caps, the key caps that are thinner than paper... other than that, it's okay.

The keyboard is very good. However, the keycaps make a strange metallic sound like a spring after you stop pressing the key; you don't feel it and the only way to hear it is to be close to the keyboard. It doesn't bother me because it's almost silent, but still, I would prefer it not to do that
