I would like to share my experience with the Fiizreal X50 device:

Pros:

Strong blowing power: suitable for cleaning circuit boards, air purifiers, microwave ovens, radiator fins, and blowing dust out of corners.

The magnetic head holds firmly even under strong airflow.

Also useful for dusting and cleaning garden tools, provided the appropriate nozzle is included in the kit.

Cons:

Although the battery is theoretically rated for about 2.5 hours, in practice the device overheats within 8–10 minutes and the thermal switch forces it to pause. Continuous use is therefore not possible.

Contrary to the description, the battery drains quickly: less than 1 hour, more like about 30 minutes of actual runtime.

It cannot be used while charging.

The suction function is weaker, and the dust filter slightly reduces its performance.

Technical notes:

Airflow: approx. 57 m/s

Battery: 8000 mAh

Runtime: nominally ~2.5 hours, actually shorter

Charging: 15 W

Summary:
Overall, the device is very effective in small areas and provides strong airflow, but due to overheating and short actual runtime it is better suited for short, targeted tasks.

Τoo good air pressure, makes enough noise at maximum speed

The product, so far, looks good. I received it in a few days.

very good and very good service

Kiváló

Das Gefühl, als würde ein Mini-Orkan durch meine Wohnung fegen, ist einfach irre befriedigend. Kein Vergleich zu diesen schwächlichen Plastikdingern aus dem Baumarkt!

Les buses en aluminium survivent à tout – j'ai même testé accidentellement sur une tôle ondulée, aucune rayure!

Tegnap a kempingben sátor felállítás előtt szárazra fújtam a nedves földet, ma meg a kocsi hűtőrácsát pucoltam – annyira egyszerű váltani a fújkákat, hogy még a 8 éves fiam is megtanulta.

Gdy się rozładuje, podczas lunchu ładuję i po godzinie znów działa. Idealne dla zapominalskich jak ja
