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

A few months later it began to make noise - I never give anything for repair - either I repair it myself or throw it away. I'm not a professional in analyzing technology - it's just interesting how it works inside) Until you see what's inside, you think that everything works on magic) To disassemble it, I had to purchase special long screwdrivers in Leroy, with a rod in the middle I unscrewed it - disconnected all the contacts, removed the motor, lubricated it - everything is ok - it stopped making noise. Just spraying silicone grease will not be enough - you need to apply thick grease to all places where the fan rod is) Well, in general, everything was done in 2-3 hours. The hardest part is putting it all together. The difficulty is that you need to twist everything, then connect it in very uncomfortable positions - if you have small hands, it will be easier. But half an hour of training, 50 attempts and all the rules came together)
