My First and Last Keyboard Best thing EVER

iI recently came across a keyboard that I decided to build using Chosfox White Linear switches. Having never built a keyboard before, I was pleasantly surprised by how quiet it was when typing. The only issue I had was with the unlubed stabilizers. Despite this, I found the keyboard to be a beast in terms of performance and my friends who introduced me to this hobby were impressed by the amazing THOCCCC it had. The keyboard is made of high-quality materials and is easy to set up with plug-and-play functionality. Overall, I was blown away by the Chosfox keyboard and would like to thank them for an exceptional product. Thank you So Very Much Chosfox
