I have given the advise and pump only an acceptable rating. The reason being I am using it in a protected dry situation and whilst it works fine there are a number of wasted component parts designed for under water use only including the emphasis of having an "eco" mode which I was falsely advised and given a calculated how much I would save in running costs and pay for it self in 5 years, even though I gave the correct info being used in a dry setup in conjunction with a Proficlear Premium Compact EGC, and was recommended over the Aquamax Dry pump, which apparently are being phased out with no "eco" mode. Also the useless tiny rubber feet just fall off if touched even though fitted correctly.
