Worked great with my ts601. I had to update the software on my device to make it work, but everything went smoothly. Used them to clone sensors on a Lexus Ls460. I wish they used an 11mm nut instead of a 12mm nut, but that's fine. Very high quality and high quality workmanship. I was impressed! Much smaller than original mx sensors. I thought I had been scammed and they just sent me valve stems. nope!
