Amazing keyboard, I don't really have anything negative to say about it, I got it on sale, so the price wasn't too bad. It feels great, i love the RGB on the wrist rest as well. in terms of responsiveness, it's what you'd expect from razer's yellow switches. They're not completely silent, but they're definitely quieter than the green switches. (personally, I like that). I haven't used the macro keys at all, so i can't give any feedback on those. My only concern is the wrist rest, in previous razer keyboards i had, it eventually wears out and starts flaking, those were easy to replace since they didn't have rgb, so if it happens with this one, I'm not sure if they sell them separately or how expensive they'll be, so its something to consider. It's comfortable to use. However, in my case, over long sessions, it makes my wrist sweat, which i guess is expected since it's some type of leather. I just put a cloth on it for long sessions, which makes it more comfortable for me. Aside from that, I'd definitely recommend it. 10/10.

The black widow v4 pro was chosen among all keyboards regardless of price, based on my personal criteria of build quality, programmable keys, good RGB lighting, a variety of multimedia keys and a wheel, all combined with a similarly good set of switches. In my case, I chose the yellow switches as they are smoother and quieter.

Firstly, I want to emphasize that despite the description, the keyboard is NOT wireless, which I discovered before purchasing it through thorough research and reviews (https://www.rtings.com/keyboard/reviews/razer/blackwidow-v4-pro, perhaps the most detailed review I have seen).

As you will read/notice, the keyboard meets and exceeds expectations in many aspects:
- Very good build quality, with an aluminum body and a sturdy construction. The keys, although made of ABS plastic (instead of the PBT used in other flagship keyboards), feel very high-quality with large and nice-looking letters/symbols.
- Perfect and impressive lighting, adjustable to a certain degree even without the synapse software, which allows for further customization. Even the wrist rest lights up when connected.
- The length and quality of the detachable cable (2 meters), and an optional second cable for the USB passthrough port located at the back.
- The dedicated multimedia keys, the wheel, and the jog dial, all made of aluminum, are very convenient. The dial can be programmed for up to 100 different functions through the synapse software (such as volume, scrolling, lighting intensity, zoom, track skip, and more), along with 5 fully programmable macro keys and 3 additional ones on the left side.
- The magnetic detachable wrist rest is very convenient and comfortable, and it follows the lighting of the rest of the keyboard with a perimeter LED line when connected.
- The yellow switches provide a very nice typing experience (I am writing this review because I wanted to enjoy the keyboard). They are relatively quiet and have a very good response. They might feel a bit sensitive at first, but I believe it is something that can be pleasantly accustomed to.
- Additional details: adjustable rear feet with 2 levels of tilt (up to 9°), a game mode that disables certain keys and combinations, very low latency with an 8000Hz update rate, N-Key rollover and anti-ghosting, on-the-fly macro programming, nice and discreet LED indicators for caps, num, and scroll lock.
- Negatives: The very nice multimedia buttons do not light up, so until you learn what they do, you have to somehow see what they symbolize. It's a very minor detail, but it bothered me a bit. The installation of the synapse software did not work, and I had to make an exception in the firewall for it to function. Again, a small detail, but for someone who doesn't know, they might give up and not bother with the synapse, thus missing out on its advantages. It's a slight flaw on Razer's part.

In summary, in its category (200+€), there are not many options available. The K100 RGB, the K70 MAX RGB from Corsair, the g915 from Logitech, and perhaps the ROG Strix Flare II from Asus. Each of these keyboards lacks some of the elements I mentioned above, although some of them have certain individual features that are slightly better, such as wireless capability or PBT keycaps. However, overall, I believe the Black Widow stands out. If cost is not a factor, it is one of the top choices, if not the best choice. I highly recommend it.

The photos due to a broken camera do not do justice to the beauty of the RGB on this keyboard. COLORS, very strong lighting, it is simply impressive.
I got the keyboard about 1 and a half months ago and I have absolutely no problems. Of course, time will tell if, with a v4 and its price, it allows for any appearance of a problem. In general, yellow switches have an incredibly fast response to pressing, so much so that I often accidentally touch keys and they register (and when I say touch, I mean without any pressure), which I find positive for gamers in particular. It is a keyboard that you will find difficult to get used to due to the side buttons and the extra button extension on the left, as you will constantly press them in the first 2 weeks (I still make mistakes), but it can be managed and you can get used to it. You can set anything you want on the extra buttons, from modes in Synapse to keybinds/settings/quick message, literally anything. Very sturdy construction, which justifies the money you spend, heavy, stable, and the wrist rest is soft and comfortable. At first, it didn't suit me because it lifted my wrist too high, even though it relaxed me, but now I can't do without it. The RGB goes all around with the wrist rest, except for the back where it is not visible, it doesn't bother me but I would have liked them to extend it more for the money. The wrist rest is magnetic and doesn't go anywhere, 10/10. It has a detachable cable, so in case of cable damage from an active pet, you don't need to change the whole device and pay for psychologists afterwards. It has an extra port on the back and also has buttons on the side that you can set as you wish.

In conclusion:
Is it worth the money? Yes!
Would I recommend it? Absolutely! (For non-budget-friendly users)
Construction? 10/10
Appearance: 10/10
User-friendly? Yes, with many options for settings, many extra buttons (volume wheel/playlist skip, pause, back, etc./keyboard lighting intensity adjustment button/zoom button [perfect if you are a content creator, 10/10] and the extra buttons on the keyboard extension)

Also, if you are looking for a compact keyboard, don't even consider this one, this keyboard is massive, bigger than any other I have seen.
That's all from me!
