To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I am amazed at how well these work and for how long they work. I would have never thought that they would continue to work like new after 6 months.. After using one pair for 6 months to see how it performed, I immediately purchased more even tough my first pair is still going strong. Just a wonderful product.
Use these for my leather dress shoes i wear daily. They previously smelt terrible, but after leaving these in there over night for a week I can put my nose right into them no problem. I have used two balls (one for each shoe) for about 2 weeks and the balls are still in full effect. Definitely would buy again.
I think the greatest testament to this product's effectiveness is that they eliminated the odour from my rock climbing shoes, which get quite rank. They worked perfectly as advertised and now I don't have stinky shoes! Can't recommend them enough.
Makes bad smells disappear. Only bought the 6 pack because i had bought 1 pair that lasted over a year and i am hoping the 6 pack do the same. It would be a great value purchase if these last close to a year.
