Muy buen funcionamiento del producto y muy silencioso

I bought this for my first pump for a 4x4 tent with 4 plants. It is..........loud, to say the least.HOWEVER, I should have done my research first, as this is a commercial pump and wasn't designed for my intentions. If i decide to move my tent out to the garage (outside of hearing range) this pump will be amazing. It is as powerful as it is loud, and supplied and insane amount of pumping power which could be amazing for my uses, but ONLY if it is outside of ear-range.Consider your needs and setup. If noise is not an issue, this is great. If noise is an issue, consider a less powerful pump.EDIT: I needed an extra pump and so I gave this one a shot despite the noise - IT'S ONLY CRAZY LOUD WHEN THE STONES ARENT HOOKED UP!!! I feel pretty dumb. This thing is super-quiet and insanely powerful. I only figured this out near the end of my grow, and I regret not exploring this thing further. I had a HydroFarm 4 outlet and another smaller 2 outlet connected before I set this one up, which conveniently has six ports. I now have 2 spare air pumps after replacing them with this model. I want to reiterate: this pump makes less noise than both my other pumps running and provides approximately four times the power Very impressed.SECOND EDIT: Bought a second pump which was insanely loud, even after hooking up the air stones. I struggled with the noise for a long time before I took off the black cap and saw that the rubber gasket sealing the case was folded over itself, allowing air leaks and intense vibrations. I attempted to re-fit the rubber gasket, but realized it was slightly too large for the frame it was meant to wrap around. It may have stretched, or it may have just been a defective ring. I pulled the ring out and replaced it as best i could, which greatly reduced vibration and noise. It is now only slightly louder than my original pump, which is acceptable to me, and I am pleased not to have had to return it at this point, because these pumps really do work very well, especially with the 6 outlets per pump. Still pleased with the product, despite the initial headache.

Kind of loud but lots of power

This machine has a lot of power. Alot more than what I expected. It's a little bit on the noisy side but works excellent
