I just got my CG LOCK and it's everything they say it is.
If you don't know, they are a restraint device that clips onto your seatbelt to really sinch you in for the twisties. Do a search for photos.
I bought it from the manufacturer and I'm glad I did. John in customer service is going the extra mile for me. They sent me the (curved) clamp and not the straight one shown in most photos and on thier site. I didn't know there was a difference.
The curved one doesn't seem to fit snug enough on our WRX's seat belts, but I'm using it until the other (straight version) arrives.
He is sending me the straight one and letting me try them both without buying the second one. He's not even charging me and sending it DHL 2nd day delivery. Of course I'll send back the other ASAP. Service like this has to be rewarded with the utmost honesty. Most companies will just say to send the old one back for credit and then we'll ship the new one in our own sweet time and you have to pay to ship it both ways again.
I highly recommend the product and buying it from them directly should you have a problem.
