Fixed them... The flow is up to my expectation, It can easily cover a 3ft distance even with the diffuser, Without the diffuser the flow is too harsh even for sps... Bad part, is that the duration knob is very inaccurate, if you have OCD like me you will be fine tuning it the whole few hours just to exact timing... LOL...
I am quite okay with it at that pricing although it cannot be controlled...
