Very high quality and great service. I have been looking for a rope style seatbelt attachment because my dog knows he can chew through a flat leash/seatbelt in seconds, but he won't bother trying to chew a rope. Would love to see an auto-locking biner on this, would make it a bit easier when trying to wrestle my dog when he's excited to get to the dog park. Also, my dog unbuckles himself when he steps on the seatbelt and has freed himself a few times, despite the buckle being hidden under my seat protector. As a workaround, I buckle in to the buckles on the seat next to where he sits, which makes the seatbelt a bit shorter but seems to work. This is more a function of my car (toyota rav4) seat belt placement and not a defect on the part of the Tuenne seatbelt.
