I have not been able to sleep without a fan on for years. I have even taken a desk fan with me on vacation multiple times because I can not sleep without one. I bought the V6 to replace my bigger desk fan that sat on my nightstand. After just plugging it in about 10minutes ago I see several problems. 1. It is very noisy. I know the high setting would not let me sleep. It seems to make a 'static' kind of nose like there is something stuck in the blades. But I can not find anything at all. I believe it is in part with the 3 blade design and the grill design, but, I did not engineer it so I do not know. 2. It is hard to change the speed.You really have to hold it and use the knob or get your finger in between the slots to change the speed. Overall out of 10 I would give this a 5 1/2. I could see it as a good desk fan for me at work but when I am trying to sleep I could see this not being able to let me sleep.
