"A large-tank smart humidifier with commodity electronics and no brand reputation."
The '300ml/h output' means it's powerful enough for a large bedroom, but being an ultrasonic model, this output will include any minerals from your tap water, creating white dust.
This is for a buyer who prioritizes a large tank and smart controls for the lowest possible price. If you understand the need to use distilled water and are willing to risk a no-name brand for a bargain, the specs are compelling.
Anyone with hard tap water who isn't prepared to buy distilled water should skip this. Buyers who value long-term reliability, customer support, and a polished app experience should invest in a product from an established brand.
