Me gusta mucho. No necesita software adicional, y se siente muy robusto. Las luces solo son en blanco, pero por eso lo pedí (no me llaman los RGB). Falta acostumbrarme al teclado numérico combinado con las flechas y las demas teclas, pero ya sabia que venía así.

5.0 out of 5 stars Compact, great lights, fun to type with
Reviewed in the United States on 8 June 2018

I am very glad I got this keyboard. I have the Cherry MX Brown switches, and I like how they feel. I'm trying to learn how to type without pressing the keys all the way down, but just to the activation point. You can feel the activation point, but it doesn't make much of a sound. It is lightweight and compact enough to use comfortably on my lap. It's heavier than my previous keyboard, but it's a good, solid, hefty feeling. The layout is pretty clever and easy to get used to. I am used to leaving the number lock on with a 10-key, but you have to leave it off to have regular access to the arrow keys, del, home, end, etc. But it's not a pain to hit the number lock when I need the 10-key.

The lights look great. The lighting is even and consistent, and a good, pure shade of white. You can adjust the brightness. It has different light shows that it can do, if you want it to. And, you can vary the speed of the light shows, which is neat. You can create your own light shows, too. The black keyboard with white lights just looks nicer, to me, than RGB. I haven't used it for gaming or tried to use macros.

I also really like that it comes with a detachable microUSB cable, as I needed to buy a longer cord to use it from my recliner. The cord that comes with it is nylon-wrapped with gold-plated connectors, and very nice. However, it's just a little too short for my needs. So, it is nice to be able to use different size cables with this keyboard and not need to use an extension cord, which can be kinda iffy with some keyboards, sometimes.

5.0 out of 5 stars Love the medium size
Reviewed in the United States on 23 March 2018

Love the medium size, love the authentic Blues. I love especially the fact that they kept the freaking 10 key! For those of us that actually work for a living on our computers, 10 key is nigh indispensable. I've actually already found myself using the double zero with a particular vendor who always insists on having a double zero on account numbers.

I got this thing at about $80, so keep that in mind, it looks like it shot up $20. $80 is a perfect price point in my mind for the compromise of the mid size and the fact that the LEDs are white, as you can get something like an MK Hue with aluminum board and Outemu switches for $40-$50 and lighting. Cable is braided, a single USB 2.0, by the looks of it. The plug in under the keyboard is slightly awkward, but not a big deal. Has cable management underneath the board, mine is hanging out to the right at this moment, very nice. Does have padded extendable feet, although I never use feet.

The board feels super solid. It's tall compared to the other four boards I own (KM570RGB/Velocifire VM01/MK Hue/LearningTech Tenkeyless for reference) Lighting is extremely bright and doesn't cheap out on the settings. I'm too lazy to check right now, but I think you've got four brightness settings, plus off. This makes a great professional keyboard for someone who wants the quality of a good solid board, wants lighting for night work, and the fun of typing on blues, all without looking like a teenager's "gamer" keyboard. If you need the small form factor, I think this is far better than tenkeyless, although it definitely exists in the mid range in terms of size. It's not the most portable thing on earth compared to my tenkeyless, but it would work if you're just hopping in the car, especially with the detachable cord. I keep wanting to get back to my G.Skill with brown switches and RGB, but I can't bring myself to do it...

4.0 out of 5 stars Masterkeys Pro M, a decent full-featured, semi-compact board
Reviewed in the United States on 18 July 2019
Verified Purchase
For years I typed on a Cooler Master Quickfire Ultimate full-size board, a fairly rare version with brown switches and a white backlight. I rather enjoyed that keyboard, despite having a few childish "gamer" features, and I would have preferred heavier switches with a more pronounced bump, but it got me through a lot of work. Then I started using a 3DConnexion SpaceMouse Pro, which made my keyboard tray a little crowded. I didn't want to go with a 10-keyless board because I use my numpad a lot, particularly when using CAD software alongside my SpaceMouse. Enter the MasterKeys Pro M.

OVERVIEW
The MasterKeys line seems to have superseded the Quickfire line in Cooler Master's catalog, with this particular keyboard, the pro M, taking the place of the Quickfire TK. It lacks the three columns of keys usually occupied by the inverted T arrow keys, the Home End etc. block, and the Print Screen/Scroll lock/Pause keys (which I will collectively call the "nav group"). On a standard full-size keyboard, these functions are replicated in the numpad (in fact, the numbers were alternate functions; the very earliest PC keyboards also lacked the nav group and relied on the numpad entirely for navigation) but a couple generations of us were raised with the Model M pattern ANSI keyboard layout, so just deleting the nav group would take retraining. What Cooler Master has done is split the numpad 0 key in half into 0 and 00 keys, allowing the nav group to be arrayed differently onto the numpad in a more familiar layout, with the inverted T on the bottom, Insert/Delete/Home/End/Page Up/Page Down in their familiar layout on keys 4-9, and Print Screen, Scroll Lock and Pause on the /, * and - keys. You simply toggle between these functions with the numlock key. As a result, the Pro M is 2.5 inches narrower than a full-size board while retaining nearly perfect functionality. All of this was true of the Quickfire TK board as well, though there have been some improvements to the Masterkeys series.

STYLE
The Quickfire series was already rather understated and grown up for a "gamer" board, and the Masterkeys series is even more mature. The slight jimping around the edge of the case is still present but even more understated; it took me awhile to even notice it. The big obnoxious tribal tramp stamp Cooler Master was trying to use as a logo for awhile is thankfully gone; the branding on the board is now limited to the hexagonal typeface logos that replace the Windows glyph on the Super keys. The lock lights are reduced in size and aren't as big and hideous as they were on the Quickfire series. The key legend has also significantly improved; the angular, slightly stylized typeface has been replaced with a more straightforward sans-serif font, and the big negative blocks that denoted the on-board feature controls are gone, replaced with simple positive legends. Unlike my Quickfire board, my Masterkeys board has no large glaring white spaces, only crisp white-on-black lettering, which gives the keyboard a sleeker and more consistent appearance. Overall it's a rather professional looking board.

FEATURES
My Quickfire board was a typical full-size board that had a simple backlight that could light the whole board, do that breathing effect that they all do, and it could light only the wasd and inverted arrow keys because gaming. It also had selectable 6 or N key rollover, selectable repeat latency, and media keys available through the FN key. That was it. Being a Linux user, I was attracted to this simplicity as it required no software on the computer to operate.

By contrast, the Pro M is more feature loaded. The backlight is more involved, with each key being individually addressable. It has many more lighting modes including some that react to the user's keystrokes. It even has a built-in Snake game that is played with the arrow keys on the lights of the keyboard. Much of this is just gimmicky eye candy, but it also has a mode that lets the user choose which keys are lit, nice to just light the home row. Control for all of this is done on the keyboard itself; there is no software to load on your computer which makes it perfectly cross-platform. They do have an SDK available for those who want to "hack" the board by coding their own modes in C++, but it isn't required for running the keyboard. This keyboard automatically selects between 6 and n key rollover on the fly depending on whether you're holding down more than 6 keys at once, and it still has the selectable repeat latency. It does manage to squeeze in some media keys, but it's missing a dedicated mute button despite having pleny of room for one on FN+num3.

It also features a Macro capability which frankly arrived stillborn. The documentation with the keyboard doesn't explain how to use it, and when you figure it out you find that macros are played back in real time at the speed at which they were recorded. This is probably an anti-cheat feature so that gamers couldn't enter inhumanly fast commands into games, but for those of use who are typists that have common phrases to re-type all the time, it really doesn't help. The macro function does light up the keys it is pressing, and it can be set to infinitely repeat the sequence, so it might be handy for a Halloween set piece, that's about it. Truthfully, it's better to use something like AutoHotKey for such things and let the keyboard just be a keyboard.

Finally, the MasterKeys line features a standard bottom row, making replacement key caps easier to find than the atypical arrangement on the Quickfire TK. The Mini-USB plug is gone in favor of Micro-USB, and the cable routing scenario on the bottom of the board has been simplified and improved somewhat. Some say that the straight-through out the back routing makes it easier to accidentally unplug the keyboard, but I've got about 2 feet of extra slack in the cable, so I'm not so worried about it.

MY IMPRESSIONS
Overall, I feel that Cooler Master has significantly improved their product line, this board looks a little more adult and fits a little more in an office than previous models did, loud mechanical switches notwithstanding. There are a few things lacking; the brightness controls don't work in the custom-light mode. Maybe I want a dimly lit home row? Num1 and Num3 have no alternate key bindings at all, despite how handy having a Tab and Escape key on that side of the board would be. And as I've said before, there is no hardware mute key. The lock lights are stacked almost vertically, which makes it difficult to tell which is lit, though in practice I never use caps or scroll lock so it's not much of an issue. Still, I would space them horizontally as is the standard; there's room for them to be spaced that way.

Despite the improved nav layout in the numpad, this keyboard does take some training to get used to. The arrow keys are in the same relative space as on a full-size board, but I find myself trying to feel for the gap above the left arrow to locate them, a gap which is filled with Num1 on this keyboard. I end up pawing for a feature that isn't there and end up looking down to center my hand. Delete, Home, End and the rest are one row down, so if you're used to Delete being next do backslash, you're going to end up striking Insert by mistake. On the other hand, I have noticed that--when using the arrow keys to navigate around something like a terminal menu or something, your pinky rests conveniently on the Enter key. Where has that been all my life?

Best practice for using this keyboard is to usually leave numlock off so you can get to the nav keys, and strike the numlock before and after entering numbers. If you're in the habit of just leaving numlock on 24/7 like I am, that's going to be a bit of a change. If you get used to that change, you can simply adapt your typing style on other keyboards by just turning numlock off.
