I used one for a while, regret I ever bought it. It actually developed a leak, not sure how, as I never moved it but a small hole developed in the bottom plastic, I suppose from the pressure, and one day leaked half my tank on the floor while I was in another room. The one I used was TMC V2 1000 sandbed filter connected to an Eheim external powerhead, both were outside the tank.
The flow through it also was fluctuating often enough for me to play with the valve every couple of days to adjust it. It was either too high and spit sand out or too low and wouldn't fluidise to the recommended line. Obviously the prefilter needed meticulous cleaning as it affected the flow in a few days and it's kind of hard when one needs to keep it constant to keep the sand stirring at that fluidisation line.
By the way, I used it in a heavily planted tank, for a year and there are no downsides in regards to plants. They grew lush, didn't care what filter was running inside the tank.
