Review on Marsheepy Activated Purifying Deodorizer Chemical Free by Olga Porter

Just received a few days ago so can't comment on durability but so far I love them! Slightly smaller than expected but in a good way - fits perfectly in daughter's volleyball shoes and uses one for each knee pad - smells GONE in a day! I hung it next to the tray - I haven't smelled it yet! Put a pair in each car... I tested this further by putting a pair in the garage where I smoke - one right on my bag and it works great! I installed them outside and was concerned because it's below freezing outside - don't know if it was just the sun or if they needed heat so I googled it and said it just needs UV light - the temp plays not matter. I will update after a few months of use but very happy so far!
