Review on BONECO U350 Ultrasonic Humidifier: Warm or Cool Mist, Top-Fill Efficiency Unleashed by Guanyin Lin ᠌

I own two humidifiers: Boneco U350 and U330. The first U350 lived for a month and a half and then died. The second U330 was taken to replace the first one (less electronics, no hydrometer, so there was nothing to break) broke down after two weeks. Both times the same symptomatology, which is best described as "brain baked". Both, shortly before death, began to flash all the indicators, click until they completely turned off. The service center at the U350 admitted the failure of the main board, could not replace it due to the lack of a board, and offered an exchange or refund. The second one is under warranty today. Two humidifiers of the same series that died in a row - this is very similar to the marriage of a series. Indirectly, this is indicated by the refusal of one of the centers (still hangs on boneco in the list of centers) to continue working with Boneco, and the other center says that the minimum repair will take 30 days due to workload. In reality, you can pass only in Rusklimat on Narvskaya 21. Noise. This, of course, is not so important against the background of terrible fragility, but the noise turned out to be the most annoying factor. There are two problems - at full power it is loud, seriously louder than my old Boneco, which served 5 years before, the sound causes discomfort at night, but you can live with it. But what is difficult to put up with is the sound made by the device when it runs out of water. At this moment, the pump for pumping water from the tank to the working volume starts turning on / off with an interval of 10-15 seconds. The device clicks rhythmically, trying to double-check that no water has been added to it. And it would be nice if he did this several times and stopped, but instead, the clicks continue until the winning moment, until you add water. And since a full fill of 4.5 liters is enough for 6 hours at maximum power, you (and everyone in the room) are guaranteed to get up at night to add water, because it is impossible to endure this sound. I was saved only by lowering the power, so that there would be enough moisture for the whole night. The problem is the same for U350 and U330. The hydrometer is useless. Overestimates by 20-30% of the external.
