Yea! Yea! I put it in today and everything worked great! the seat belt went through the "stool" and tightened real good. Mine is the shoulder and seat belt in one, so had to use that metal clip to keep it tight. I put her harness on and then connected it with the leash I tied like crazy to the "bin" part. You would not believe how well it worked. She is at window level or a little above, so she can look out and see the world going by. I'm so happy! And she is now safe-----and so am I!
