After a couple of uses it stinks every time we open the lid, even when it’s hardly full. I’ve even tried using 2 sachets but it’s just no good. Will be trying another brand next time since this just doesn’t cut it. The only positives are the convenience of the sachet and it does break the waste down quite well. Unfortunately the smell is just too big of an issue. We’ve even tried just with number 1 but it still smells bad, not like other brands we’ve tried. ## Frequently Bought Together - Walex Bio-Pak Black Holding Tank Deodorizer & Waste Digester Drop-Ins - Advanced Enzyme Formula for Rapid Breakdown of Waste & Paper, Removes Odors & Cleans Tank; Tropical Breeze, 10-Pack - Scott Rapid-Dissolving Toilet Paper, 12 Double Rolls, Sustainable, Septic-Safe, Toilet Paper - Walex Porta-Pak Black Holding Tank Deodorizer & Portion Control System Drop-Ins - Rapid Breakdown of Waste & Paper, Odor Prevention, Cleans Tank & Sensors - Fresh Scent, 10-Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/53473728-bio-pak-black-holding-tank-deodorizer-and-waste-digester-drop](https://www.desertcart.be/products/53473728-bio-pak-black-holding-tank-deodorizer-and-waste-digester-drop) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-15*
