Awesome products & service!! Not only provides a safe and comfortable drive ( for pups and people) but also contains pet hair to the PupSaver which is easily cleaned up with hand-held vac. VERY pleased with this solution to driving with the pups. If using the J-Hooks, you can easily set up and remove the PupSavers quickly if have to carry more people in vehicle. My 2 pups come to the office with me daily and the PupSavers are so much more comfortable for the pups and take up MUCH less space than crates. I have a large and small size in 2nd row seating of a GLS 450. If I need to transport a lot of large objects, I can easily unteather the PupSavers, nest the small into the large, and tuck them into the front passenger footwell, leaving the whole cargo area open....something I couldn't do with crates. Quality product built too last!!
