I would ask the vendor the question about suitability for use on 230V. Then, if it's wrong, it's his fault!
I do like this extract from that travelwiki link:
The electrical engineer's maxim: The smoke that escapes from a device or a component is its spirit without which it cannot work.
In other words: if smoke rises from the device, then it's destroyed.
And (more specifically)
The first time you use electrical equipment on a voltage system you haven't used before, watch for excessive heat, strange smells, and smoke. This is especially true for those residing in countries with 120V (USA, Canada, Japan, etc.) visiting places with the higher voltage. Smoke is a sure sign your equipment cannot cope with the voltage system.
