    Great pump but beware Amazon Warehouse deals on this item
  

*by H***A on Reviewed in the United States on May 20, 2014*

The good, very quiet pump.  I am running 2 of these (red ones, same pump) in the wet/dry sump of my 120G aquarium.  both of these together make hardly any noise.  They are replacing a RIO pump that has about the same flow as these 2 combined at it is very noisy compared to the L40s.  (as the aquarium is in our bedroom, being quiet is a plus!)The only bad thing I have with these pumps is the way hose fitting tightens around the hose.  Unless you use a very thick hose, the tightning nut does not do anything.  I had to place some extra hose piece down in there for the nut to actually tighten. (Don't want the hose to blow off the pump!)The "othjer" bad - ordered this through Amazon warehouse deals as used - Very good condition.  It is being returned as the impeller is not glued to the magnet, so it does not pump any water, just makes noise from the loose impeller.  So sometimes the returns they resell were returned for a reason, they are broken (& not properly inspected before reselling to someone else.).

    Not Really an External Pump, but a good submersion pump.
  

*by N***Y on Reviewed in the United States on November 24, 2010*

The pump is advertised as working in and out of water.  However its working out of water is a bit of a lie as it can't prime itself and can't pump any air.  This means it only works out of water if it is located below the water levels that it is both pumping from and to, and even then you have to manually prime it.  In most cased if you ever lose power you will have to re-prime it.  So yes it technically works out of water, but not in the way an average person would expect a pump to work.As for the pump itself, if mounted correctly it is very quiet and seems to work well.  Since it is an induction motor pump it only has one moving part so I expect it to last for quite a while.I find it hard to just give it a 1 star because they exaggerate that it is an external pump.  Certainly for an external pump I would give it a 1, but for a submersion pump I would give it a 4.  I suppose I should be lenient and give it a 3.

    Great value! Very quiet and reliable!
  

*by A***. on Reviewed in the United States on July 28, 2019*

I don't know why this pump has so many negative reviews. I've had a L20 for nearly 2 1/2 years now and never had a problem, so I'd say that qualifies as being reliable and a good value. I use it submerged in a bucket to transfer reconstituted RO water to my aquarium for water changes. From the floor to the top of the aquarium is just over 4 feet, which the pump handles just fine and it hardly makes any noise. I'm sure there are more powerful pumps out there, which some people may have a need for, but I don't. All I have to say is that compared to all the work I would've had to do lifting buckets of water by hand, this thing has paid for itself many times over!
