## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Why did these leave the market.  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.

    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

    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.
