Comments on XCJZ Chocolate Ball Bearing switches | Comments on HMX Lunar Stone switches |
The Chocolate Ball Bearing Switch features a new integrated ball bearing design, with four embedded bearings in the stem that glide along internal grooves in the top and bottom housing, delivering a smoother more consistent linear travel – SerpentKeys. | The HMX Lunar Stone linear switches are manufactured using HMX's brand-new full POM housing mold. It is the first full POM HMX switch. As the first full POM HMX switch, we expected it to sound and feel a bit different from other HMX switches in the market. They have proven to be quite unique; They sound fuller and thockier than most HMX switches yet still come with the bassy bottom-out sound. The travel feels very smooth yet there is audible scratch since that's what most people love about full POM switches – Unikeys. |
