I originally bought 4 Jebao WP40's and all but one have now died. Seems they only have a lifetime of just over one year (not good). Have replaced them with RW-15s (pumps only). They can use the same controller and power supply as the WP40s. Hope their lifetime is longer than the WP40s.
Otherwise I like the Jebao pumps, good flow and low noise. Good thing they are cheap...
