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

Bought a used car that had a potent fragrance from the dealer. Tried coffee, baking soda and multiple days with doors open to air out. This product appears to have resolved my problem.

Good selection of disinfecting products that actually work.

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.

After the Creek Fire in the Sierra National Forest several years ago, my cabin in Shaver Lake was permeated in smoke smell. I tried everything to remove the odor but nothing worked. I found your product by accident and decided to give it a try. What an amazing difference it made. Clean fresh air and no smoke odor. I have since used it in my cars and homes as an addition to my normal spring cleaning. Amazing product. Thank You. Mike Y. Shaver Lake Ca.

We needed to get rid of smoking smell, it worked but left a strong chemical smell. Good news we sold the car but couldn’t get the chemical smell out. Put in a car air freshener.
