It works with a base supplied with one fixed wire (using a plastic attached greenhouse, is it strong enough?) To an ironing board. When the iron is placed on its base heater is supplied with current and heated rapidly. By cons when used is separated from its base and there is no power. But it keeps a sufficient temperature for about 30 seconds, probably through a judicious choice of material constituting its sole.
After 30 seconds the base emits a "beep" which means that the iron must be submitted on the basis and just about 4 seconds to resume the proper temperature as indicated by a LED.
This periodical return to the base is not troublesome because, during ironing, you often stand iron to handle the machine. More importantly, the use of iron is facilitated because it is not crowded by an electric wire.
The base can remain permanently on the ironing board.
I first used this iron for ironing trousers and I did not notice any significant difference from a conventional iron. But as I rarely returns I'm not a good guinea pig.
Then my companion, who handles iron more often than I, took a positive view because it is usually hampered by the wire.
Finally we have given to a professional who makes ironing for us. She appreciated the absence of thread, but was a little embarrassed by the length of periods of 4 seconds to restore the temperature. Indeed, being very fast, usually the times during which it is based iron are shorter. If we do not take care to respect the lengths places the iron is less effective. But if we respect these constraints it works very well.
