I have been using it for over 2 weeks and has worked perfectly. The main unit feels very well built. The small pump works great but not the same quality as the name unit, it feels a little cheap. The tube holder that goes on the tank/sump is a little big and too long and too large wherr the tube goes into it. I had to it bent funny to keep it from falling out. The tube holder needs a simple redesign and it would be a perfect unit. The lens that goes on the inside of the tank may be an issue getting clogged with junk if not in a high flow zone. System seems like it has a dry protection. I had a lot of bubbles in the line and the system freaked out like it was empty, but the instructions are not the greatest. Highly recommend this product great price and works flawlessly. ### ⭐⭐⭐⭐ Works great, could use more features. *by T***Y on May 14, 2018* great inexpensive auto top off solution.Only thing its missing is an audible alarm if the unit disconnects from the back of tank.The cord pulled the unit off the back one week and I didnt catch it until my tank started sucking air in the back. At least I know now that a disconnect doesn't activate the pump! ### ⭐⭐⭐⭐⭐ NO MORE PARAM FLUXES... (Makes this a must have) *by C***R on August 30, 2019* I throughly love this product, very nicely designed and a lot smaller than intended, however this is a PLUS because it allows people, myself included, to attach this optical eye sensor directly to the tank. Being that this unit is small and compact it is great for nano setups, bought mine for my fluval evo 13.5. Also pump is low watt and very quiet and efficient which all in all makes this a beautiful design, kudos to this company for providing a wonderful product at such a GREAT price point!Buy this and you won’t regret your purchase!Update!! Months later this thing is as good as new and better than ever if something happens to it I’ll be upset, but instantly order a new one, GREAT PRODUCT!! --- ## 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.tn/products/63488803-aquarium-marine-reef-fish-tank-automatic-auto-top-off-water](https://www.desertcart.tn/products/63488803-aquarium-marine-reef-fish-tank-automatic-auto-top-off-water) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-23*
