Well worth it
Size: Full Size, Pattern Name: Keyboard
Very comfortable and robust. This definitely looks and feels like a premium item. I had bought a few alternatives that were cheaper and they fell apart quickly. This one seems to have pretty resilient stitching and the fabric doesn’t bunch up which could cause a tear. The base has a non slip texture so it’s not going anywhere without some force. The cooling feel is a nice touch too.

Extremely Comfortable Wrist Rest
Size: Compact, Pattern Name: Keyboard, Size: Compact, Pattern Name: Keyboard
Hands down the best keyboard wrist rest! Fits perfectly with my HyperX Origins keyboard, almost like these products were made for each other! I really like the minimalist design of it and the quality does not suffer because of this. The memory foam is more comfortable than the memory foam on my bed, and the cooling gel stays cool no matter how long I'm using it. I have mine on a desk mat and it doesn't slip at all, it stays exactly where I need it which is great! Whether you're someone uses a computer for work all day or just a casual gamer, I highly recommend getting this wrist rest. It will change your life!

The best wrist rest I've used.
Size: Compact, Pattern Name: Keyboard
It has just the right balance of firmness and softness. The cooling gel does keep it cool. It is durable. Its rubber grip holds it firmly on my desktop. If I need another one, I will purchase this product.

Clear upgrade from my Blue Yeti - crisp sound and sleek design!
Style: QuadCast 2 S
I used to have a Blue Yeti mic, and the HyperX Quadcast 2 S is a clear improvement. The sound quality is noticeably crisper and more natural, and it doesn't pick up as much background noise. It's also not as bulky or distracting on my desk, which I appreciate.
The RGB lighting looks really nice without being super over the top. Setup was super easy. Literally just plug it in and use it, no issues at all.
So far, I honestly don't have any flaws to point out. It does exactly what I need for calls and recording clips, while looking good on my desk. Definitely recommend if you're looking for a reliable, good quality mic. Worth the price!
