I love these. *by S***A on Reviewed in the United States on March 3, 2014* These ARE the most affordable high-flow in-tank device I know of. The only problem seems to be that the magnet seems to lose its strength over a period of a few years. I use mine as a wave-maker. I have two that cycle on and off about every 90 seconds (for years). I do have to replace the magnet-propeller assembly every few years when it will not engage when the motor powers up. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Well worth it!!! *by D***L on Reviewed in the United States on November 10, 2017* Great mod for what it is. Makes a HUGE difference in flowI suggest using magnets to secure your mj though as the suction cups are horrible ### ⭐ 1.0 out of 5 stars Algae Free, u can do better! *by N***C on Reviewed in the United States on April 10, 2013* It did not fit any of my powerheads (maxi-jets)....i spent 2 full weekends trying different variations as i have a few maxi-jets.... at no time would anything work, at all. There is not any support of any kind and in the end it was just an absolute waste of money.bought a maxijet just for this project $20... and this for $20+ ...i should have just spent $45 for Korilla - which i ended up doing anyways. --- ## 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.co.uk/products/40550013-algae-free-llc-agf77405-sure-flow-1600-upgrade-kit](https://www.desertcart.co.uk/products/40550013-algae-free-llc-agf77405-sure-flow-1600-upgrade-kit) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-26*
