It took ages to receive the item, but we are very impressed with the pump. It is powerful and has shown no problems so far.
One disappointment was that we didn't realise that we needed a connection plate. The supplier could have volunteered to supply a suitable plate at very little extra effort. We had them made in a few minutes at a machinist shop in the local town (it's just a disk, but it would have been easier to receive the ready-made plate.
