The price will drop kick your wallet..the keyboard will hug your soul.
I’ve been looking for the perfect keyboard for my desk for awhile now. I have always been mindful of how much space the things i use everyday at my desk take up, so that led to me becoming a 75% keyboard person for years. I never noticed how much i truly enjoy having a numberpad and have been looking at getting a larger keyboard. I bit the bullet and spent a pretty penny on the K98 Pro….and I must say it was worth every bit of the 200 plus dollars i spent. The quality is top tear and the rgb lights are perfect for me and not overly saturated. I enjoy the THOCKY sound of the keys…it’s not too loud or too quiet. I am already considering buying another one for work. ... show more

FINALLY - A Full Size Gravastar
I have been waiting for months for Gravastar to finally release a full size keyboard. While I am not a huge fan of the feet, I do appreciate how it fits their OG alien aesthetic so it's growing on me! I love the black color and it fits so wonderfully with my noir setup. It looks so sleek, especially the lighting on the feet! It also types so smoothly and it sounds so good. The black switches really complete the look, and it functions exactly how it's supposed to. I have used it both wired and wireless (via dongle) and have had zero lag issues. Here are some reasons why I didn't give it a full 5 stars: It didn't come with a protector cloth bag thing like it was supposed to which was a bummer, but it's not a complete deal breaker. In addition, I have noticed that their other keyboard models will include a sampling of their stock switches which is super cool right? It's unique and you get to test out what they also have to offer. What I don't understand is how they have a very limited supply of switches to buy on their website? So far, I have only seen the stock switches on this particular keyboard for sale, and a couple of their magnetic switch models that I obviously cannot install on this mechanical keyboard. Lastly, I have finally figured out how to use their web based driver with no installation needed (super useful) BUT you have to ensure you're looking for the right one as they have various web based drivers depending on the model keyboard you have versus a one fits all web based driver. All in all I still vouch for this keyboard, and would HIGHLY recommend it regardless of the opportunities for improvement. I love that they finally offer a full size keyboard, I just wish they had a more accessible option to buy more of their switches online aside from their very limited supply. ... show more

Flawed
The design of this keyboard is definitely drool worthy, and its presentation even starting with the box looks like its fantastic quality, but for nearly $300 this should be the best keyboard Ive ever used. Shortly after setting it up I started finding flaw after flaw that is going to lead to an absolute roast of this design. I am comparing this to both a Gravastar V75, and a Logitech G613. Jumping right to the bad stuff: 1) Its not a full size keyboard. They squished the width about 2" which crowds all the function keys with the arrows. 2) There is no home key 3) Even though 100% of the keys have backlighting, only about 1/4 of them have frosted keycaps to utilize it. 4) It requires use of a special web-based driver to manage the RGB and settings. 5) There is no physical button for Win Lock, however there is an option for it in the drivers. 6) I have yet to find a way to change the date/time formatting. Stuck in Military time. 7) I find the lettering hard to read on the clear caps, and the dark ones dont allow light diffusion, so Im having to buy a new set of keycaps. 8) Completely customizable, but lacks additional customizable function keys. You have to sacrifice something to customize. 9) The LCD is more of a gimmick, and not particularly functional. 10) Should include a HOME keycap as well as some generic function keycaps for customizations. The Good: 1) Its heavy and doesn't scoot around. Has rubber feet. 2) The button presses are perfect. They arent loud, just a subtle tap sound, and they do have a good pressure point that doesn't fatigue your fingers. Its a pleasure to type on and use for gaming. 3) The USB dongle is magnetized into the bottom for storage so it doesn't get lost. 4) Multi mode wireless/Bluetooth/wired gives you a great combination of hookup options. 5) I like the Cyberpunk kind of details on the keys. (But im still going to replace them) 6) Firmware updates are easy. This Keyboard has 3 separate firmwares. (Keyboard / Bluetooth / LCD) 7) Comes with keycap removal tool, brush, and socket removal tool. Includes a microfiber cloth for LCD. 8) There are a LOT of RGB options, and the keyboard is controlled separately from the surrounding base. Thoughts: I was hoping to finally replace my Logitech G613 because it's not backlit, but it's going to live on as my primary keyboard. Gravastar abandoned a tried-and-true keyboard layout for this condensed model on EVERY ONE of their designs, so you have to re-learn muscle memory in your right hand. Not having ANY custom function keys was not a good choice for a product that is otherwise completely customizable. This keyboard is still an absolute pleasure to use and will honestly probably work for most people, but the price alone makes me extra critical to its flaws. ... show more
