Good purchase...
I initially received a defective unit, but these things happen. After a quick chat with their customer service they sent another one out right away. So great customer service. The replacement unit went together very easily. It was not an ideal fit in my car (Honda Fit, 2013), but it DOES fit. I will probably do a bit of modification to the uprights so the top 'feet' can sit at an angle along the car ceiling so I can use it with the back seats still in the upright position. My dog doesn't ACTIVELY try to get through the bars, so I cannot truly attest to their restraining power. But without this my dog WOULD be up in the drivers area, so it works for me. No excessive rattling even on bumpy roads... no more than another other add-on to a vehicle. I have noticed that after a few trips you will want to re-tighten the crossbar supports to keep everything in place. They don't come loose right away or anything, but they can loosen a bit over time. Overall it does what I need it to do... just don't think you are getting something custom made that will solve all your problems. Every car is different, so anything 'universal' must be taken with a grain of salt.
