I was excited to purchase the fan, especially after reading the reviews.I purchased a larger battery and charger and a sizeable five-gallon container with a lid for the water. I sat on it on my patio with guests, who were all intrigued by the design. I turned on the fan, and it was terrific. I turned on the misting function, and the water hose took a few seconds to clear any air in the line. Immediately, the pump was extremely loud, but I waited until the hose was clear of any air bubbles. The pump noise was reduced by about 10% but remained unbearable even after the air in the line cleared. After one five-gallon bucket of water, my guest asked me to turn it off. They were excited about the misting but valued their ability to converse.I contacted EGO, and they requested a video. Of course, the video size is too large for email, so access was granted to an online file. I had to call back for a response from service, and their answer was to clean the pump and ensure there was no air in the line. Clean the pump? It is brand new and out of the box. I understand the issue of air in the line, but even as that clears, the pump is very loud.I do not recommend this product unless you have earplugs. Now I have an expensive mobile fan that works well with a misting feature that is not useable.Again, DO NOT BUY.
