Pros outweigh the cons
I got the roof bag to move myself and my kids across the country in my SUV. It worked great. I don't think I would have had a successful move without it. The only negatives were like some other reviews I had read, rain leaked in while driving down. I wasn't able to loosen the straps at the time bc of my location, but it wasn't terrible and only happened when it was very heavy rain. The other negative was the straps left a mark on my car. Scratched the paint. I may have had the straps too tight, but it's pretty hard to gauge when installing bc you just want to make sure it doesn't slide off. I would use it again.
