Anyone used an Exo Terra Light Cycle (dawn/dusk fade) unit in UK?

Hi,
Thinking of buying an Exo Terra Light Cycle unit for an Iggy setup. Have seen them for sale in the UK but when I contacted Exo Terra they told me they were not available yet in the uk and to watch out for the ones being sold as they might not be the right voltage etc. Just wondered if anyone in the UK had one and if they thought it was any good and worth buying?

many thanks.
