Pros and cons

Pros

Top filling and a wide tank opening are useful for refilling and reaching inside during cleaning.
The adjustable mist output and rotating nozzle give control over mist direction.
The stated 2.5-litre capacity and up-to-25-hour low-setting runtime may cover overnight use without a refill, subject to the selected output.

Cons

The claimed 25-hour runtime applies to low mode, so higher mist settings may require more frequent refilling.

What to know before buying

The listing gives a 25 dB noise claim and a 190 ml/hr mist output, but does not specify the test conditions for these figures. Treat the 25-hour runtime as specific to low mode, not an all-settings guarantee.
