So I wasn’t looking for anything amazing when I bought this fan. Just a small tower fan that had basic settings. What I got was a high powered random wind generating machine. Normally you’d think setting the fan on low med or high would produce a constant breeze and sound, but this fan surges at random intervals. It’s incredibly annoying and makes it harder to sleep than no fan at all. I wish I had taken it out of the box right away vs saving it for a hot day. Uggg don’t buy.
