Durock Shrimp Silent Purchased used and used for approximately 1-2 months. While having a clear tactile feel, it is quiet, so I didn't have to worry about the sound even when using it in the office. ★This is a product with some issues★ The stems (the part that the cross-shaped keycaps fit into) are slightly worn overall. Depending on the keycaps you attach, they may be loose, and some may come off when turned upside down. I personally used keycaps that were made to be somewhat tight, so I didn't mind, but please check before purchasing. ※Please note that we cannot accept returns due to the above reasons.
