Matched perfectly

"Matched perfectly"

— Alejandro O. (5/5)

Metal Arctic Blue

"I love the metal knob feel, size and material. The problem is the color. Arctic Blue is washed out, the knob looks more silver with a hint of blue and doesn’t add the wanted color to my keyboard. I think the advertising color of this knob is misleading which is why it gets three stars. If you’re considering this color just know you’re not getting a vibrant sky blue color, but a silver with a blue hue tint."

— Sam M. (3/5)

Excellent metal knob

"This knob has been functioning great on my keyboard. The kids like to twist it and it's held up well. Also, it doesn't wobble on the keyboard which is a great plus. Very durable. The color is nice too, I picked gold metal and it looks exactly like the day I bought it."

— Husein (5/5)

Super high quality, but color

"Super high quality, but color description accuracy is not there."

— Ronny G. (3/5)

Noice

"Solid quality knob, speedy delivery!"

— Alex (5/5)

It’s a knob… but a really good one!

"Got mine in Black to match my case. The knurled machining is really good as is the plating on it. The nice thick plastic insert is held in there very firmly, so I have high confidence that it will stay solidly in place."

— JCC (5/5)

A great knob.

"Feels a lot better than the stock one, and it looks great with matching color keycaps."

— Andrei (5/5)
