i had some of the boyu ones (or whatever they were called, maybe resun or something, i think they are all the same manufacturer). they were fine, but a bit noisy. also, for the price, i would probably just get koralias

I used a pair of 800gph each for about a year. They worked well and never gave a problem. Actually they where quieter then the old koralias at start and stop. they did not do the clakking sound.
