Another thing is that a lot of Europeans say that Aquabee's are cheap pumps. The only problem I have with them is the little flap that makes them pump the right way.
Yeah I saw a few people mention a 'flap' issue with the pumps but I wasn't sure what they were talking about. What would this flap be? If I go with any of them, it would be the EX-3 model. Is it worth my time researching these any further? Or take this brand as hit or miss. Some people on RC find these to perform as good as a comprible Deltec would.
