"A purely aesthetic choice that trades typing fundamentals for a specific vintage look."
The 'Retro Round Typewriter Keyboard' spec means you are buying a standard, inexpensive membrane keyboard dressed up with non-ergonomic round keycaps to achieve a specific visual style.
This keyboard is for someone prioritizing a specific vintage or 'cutesy' desk aesthetic above all else, where the keyboard is more of a prop than a tool. It's a functional, low-cost option for a themed setup with very light typing demands.
Anyone who types for more than an hour a day should avoid this. The combination of non-standard keycap shape and a likely mushy membrane mechanism will hinder typing speed, accuracy, and comfort. A basic ergonomic keyboard from a major brand offers far superior function for a similar price.
