My car had one on it when I bought it and it felt like ****, really sloppy and I kept punching the dash. I swapped it within 2 days for a skunk2 with extender but while doing so found out the shifter bushings were ruined. I also I didn't realise the tegiwa shifter was adjustable until I removed it.
Anyway, I fitted new shifter bushings and reinstall the tegiwa shifter a couple of months back and adjusted it to where I liked it. Since then I've had no problems and find it a lot better then the skunk2 with extender setup I was using before.
