The only way to get the water to come out instead of the ear-piercing sound is to hold it upside down which is dumb. I completely cleaned it to see if that was the problem and it was not. Do NOT recommend! ### ⭐⭐⭐⭐ Does let out a good amount of mist *by E***Y on January 23, 2018* Smaller then expected. About the size of a water bottle. Does let out a good amount of mist. Worked well for my desk at work or would work well on a night stand next directly next to a bed. ### ⭐ Not good. *by S***N on May 19, 2019* This was the tiniest thing ever, completely useless. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/53047980-wonton-cool-mist-ultrasonic-humidifier-250ml-usb-portable-mist-air](https://www.desertcart.us/products/53047980-wonton-cool-mist-ultrasonic-humidifier-250ml-usb-portable-mist-air) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-22*
