This keyboard is aesthetically beautiful in the space with nice build quality. However, its keys are quite bulky which significantly slows me down in typing mainly because I often accidentally press two neighboring keys together (my speed drops by at least 20 wpm, just from using it, and this is after daily use) and after a certain point of having it, the keys I pressed most frequently started to not be recognized, with this issue worsening over time (the control and A keys barely work at all now, it will be a challenge for them to work). So this keyboard is beautiful, but it's only a matter of time before it becomes practically useless if frequently used keys don't work.

Having this product in my daily life for over a year, I have formed a fairly good opinion about its positives and negatives.
Firstly, it is very stable and of high quality in its construction with good materials.
The response is immediate and the range is good.
The battery life is excellent, as I write code and use it daily for at least 8 hours. It lasts for weeks.
However, on the negative side,
It is bulky.
The keys make a lot of noise (something I knew and liked, but it is annoying for others).
Unfortunately, it started ghosting on the keys after about 2 years of use. Not on all keys, but on those I use the most, such as ctrl del enter + arrows. For me, this is disappointing as it reduces its usability.
The conclusions are up to you.

I have the keyboard for a year, the main negatives are that the build quality is poor and the battery life is relatively short (1 week).

Very good key feel for the money in terms of build quality and size, but it had issues with wireless use such as lagging until the USB receiver stopped working.

Adding as negatives that the springs are ringing (all mechanical ones do it more or less), but this one a little more. Mine came with a slightly crooked chassis, resulting in a slight limp... Also, the LEDs do not have intensity adjustment. You can turn them on or off or choose between 4 different patterns. If you don't use it, they turn off by themselves after 1 minute (unless you have the cable connected). But for 45 euros, it's a steal, as the other wireless full-size mechanical keyboards are 150€++ edit: the battery lasts a maximum of 2 days (~8 hours/day of use)

Sturdy construction, with a more limited ability for back-light effects compared to the corresponding ones (but it is not at all important) and comfortable/fast typing.
