Introducing NEW TX Stabilizers! Implementing a patented technology, kin25 of TX Keyboard has improved the design of Cherry clip-ins to minimize rattling and prevent wire pop-out (using stab stoppers included with the set). The patented design features a double shot stabilizer stem with a POM outside and TPU & POM mixture inside. This mixture helps to minimize wire rattle and bottom-out noise Q: What's the difference between the two versions? TX AP(Almost Perfect) is a later version of these TX Stabilizers compared to the Revision 3 which is 1 revision behind it. However, both are still solid hitters in the ever changing market for stabilizers. Personally, I use Revision 3 for all my builds as I only require minor tuning + lubrication to achieve stellar results+ big price point difference.
