You get what you pay for (I bought it from a supermarket a few euros cheaper than the store price here).
It works satisfactorily for what it is and its price, if the instructions for use are followed.

It is not suitable for prolonged continuous use. It takes 300ml of water based on the instructions for use, and when it is empty, you have to wait 15-20 minutes for it to cool down before opening the top cap, which also serves as a safety valve.
The tank can hold more than 300ml, but if you fill it, it will spit out boiling water and there won't be enough space for the steam.
It has several accessories and a long cord. It also has a small tank for detergent on the base, but I haven't tried it yet.

It is sufficient for disinfection mainly and light cleaning on small to medium surfaces. The steam pressure, although satisfactory for its size, is not enough to clean stubborn stains.
For heavy continuous use and very stubborn stains, get something else that can hold more water and has a higher quantity and pressure of steam.
Also, do not expect to clean the entire house from top to bottom with a device that costs 30 euros.

I mainly use it for disinfecting fabrics such as masks, stuffed toys, baby strollers, child car seats, fabrics on chairs, and generally small surfaces, at most a mattress once every few months

Bad purchase, very heavy, no steam intensity, takes too long for the water to heat up, in a few words, money wasted...

Bad purchase! The water runs out and in order to open the valve to put water, you have to wait about 20 minutes for it to cool down. It dispenses detergent without pressing the button. Even some white letters on it faded after 3 uses!

Flawless for its price, powerful steam for a handheld steamer and has space for detergent at the bottom. It is definitely worth it!!
