Reviews

Excellent color

"I built my keyboard with a green, metal top frame and it is fantastic. It shines well during the day and night against my screen's light. The material and paint have held up well over the past year. Very pleased with my purchase."

— Husein (5/5)

They arrived in record time

"They arrived in record time considering the current situation, where simple to install and Incredibly high quality"

— Alexander G. (5/5)

Not recommended

"I purchased silver top frame and the anodizing quality seem low standard. For me not worth $50 for the silver color. Not sure how well spray-coated/anodizing on other colors."

— Daniel H. (2/5)

Excelsior

"Excelsior"

— Ronny G. (5/5)

Midnight Blue + Ink Noir = Perfect

"The Midnight Blue top case along with the Ink Noir keycaps and some yellow-orange backlighting is amazing. By far my favorite keyboard aesthetic I've had."

— Fox (5/5)

Arctic Blue is a lovely color

"You can change your top cover to match your keycaps. I have Arctic Blue with the GMK Agent 01 keycap set (which is white, dark blue and light blue). It looks good to me. This is on a black base, but the base really doesn't impact how the board looks mostly. And black goes with most things anyway."

— Chris H. (5/5)

My daughter loves your keyboard

"My daughter loves your keyboard parts. she even made me a keyboard for work. They are quality parts and the best keyboard I have ever had."

— JoAnn S. (5/5)

The frost is only clear
