Does anyone use one of these booster pumps? Are they noisey?

Flow rate: 2 litres per minute.

Does not say if this is open or 2 litres when at 70 psi.

If open then as you increase the pressure then the flow rate will drop to 50% so 1 litre a minute going in.

So you need around 1.6 litres a minute for a 300 gpd to function well. You may be better off with tap pressure.

Are there better ones out there?

I've been using an old Surflo pump on a 12v power supply and running it real slow for two or three years to good effect but it's beggining to show signs of giving up.  I would prefer to use a purpose built product if possible when it goes.
