I was very excited to try this product as I will be traveling cross country and wanted a smell proof stash to have along the way. The organization and size is absolutely perfect and the odor control was very good. However, on a test run over a Thanksgiving drive, my partner and I could smell our stash...subtly, but it was there. I give it a 90-95% odor control. If it was 100%, this would have received a SOLID 5 star review.
