Is it just me or is the rio like 5 -10 times as loud as the stock pump? Mine makes a loud buzzing noise. Do you think i got a bad one? Thanks
 
The Seio have worked well for me, but the regular Rio's have all been bad; I purchased 25 of varying models and each one burnt out in less than a year.
Even the free replacements burnt out.
