Review on Rubber Duck Clips for Collyon Helmet, A/C Air Vent Car Freshener with Alcohol-Free Fragrance Oil - Cute Interior Decoration Accessories with Light Fragrance for Car, Car Vent Air Fresheners by Tommy Willis

The little duck figure for the pubg helmet is very well made. Better than I expected and very strong. A small propeller, when properly positioned in front of the vent, gets it spinning. The small wire goggles he wears need to be bent and straightened to fit under the helmet. It comes with 2 packs of scent on a small round cotton ball that you put on the back. But it has no smell. They suggest using an essential oil or some type of fragrance oil and applying a few drops to a cotton pad and letting it sit. It should smell something. I use Airwik fragrance, apply a few drops and it works great.
