Review on Premium 4-Pack Fridge Deodorizer with Natural Activated Carbon – Odor Eliminator for Refrigerators & Freezers – Non-toxic, No Odor – Long-lasting, Reusable for up to 3 Years – Outperforms Baking Soda by Monique Franco

I included a comparison with another brand I bought. The case is much better in quality and the case is much larger. The other brand is just charcoal so it feels light and airy. This brand has added ingredients like zeolite and diatomaceous earth that make it heavy and gritty. The suction cups are useless, but that's not a problem because they can stand alone (or you can replace them). I would also like to mention that it comes individually boxed/sealed (and even the quality of this print is impressive). The other packs of activated charcoal I ordered were boxed only, meaning they could pick up toxins, odors, etc. while in storage or in transit. The packaging doesn't seem like such a big deal, but that's because it's mostly used when it's exposed to the air. I use it in my fridge to keep fruit and veg fresh (it absorbs gases that slow down the aging/ripening process). I honestly can't form an opinion on how well they work as I currently have both brands in my fridge. But I have to say that my first impression is very good based on the quality.
