Put the auto shocker in my 2020 honda civic for 24 hours. Followed all the directions to the letter. Did absolutely nothing. $32 for nothing
By Paul N.
Purchased the biocide auto shocker but it did not work on damp musty smell. Carefully following the instructions, in a clean dry interior, in the garage out of sunlight, for 24 hours the product did not appear to emit fumes or evidence of it like shown on the many videos I watched. The product may have been a dud. No response from company via phone calls and emails. They appear not willing to honor their satisfaction guarantee. Will not buy again.

Hard to review these when you don't have them. It's been a week since I ordered these and their not expected to arrive for two more days.

It did nothing
By Matthew B.
The product did literally nothing except leave a chlorine dioxide smell that's difficult to get rid of. They market this product for cigarette smoke odor - it doesn't work at all.
