Great feedback from a recent UK buyer:

Please note: Overseas buyers should be aware of their local power output (voltage and Hz) and that customs charges and additional taxes may apply.

IMPORTANT-  properly bleed your water system and pump to ensure there are no trapped air pockets. Air trapped inside your pump can cause cavitation, a lack of water pressure, excess noise and eventually pump failure.
