Question: Can  this fan lay down  horizontal?
Document: I probably should have bought a more traditional fan, round with  a propeller type impeller. I thought the "stick" config would work better. BOTTOM LINE:  Don't trust the clip to hold the fan at the horizontal.
The cable is way to short. If you have a tall table, or perhaps your table top is not near an electric cord, you might need an extension cord. Although I like the oscillation and high and low speed feature, the buttons are hard to press. They lay flat on the fan, but it's hard to press them to get them to work. Overall though, for the price and function, a good buy.
I needed to clip the fan in a position that would direct air at my face to mitigate my profuse sweating (sorry for the graphic description). Air movement was important as well as ability to clip fan in varied positions. Air movement is good. However, the clip is under springed/powered as I couldn't clip it in a horizontal position. TRUE -  with the universal joint linkage, you can position the fan in infinite positions.
It truly works great. When I had recieved it I thought it was going to be too small and weak, made me a little upset. However I used it right on my night stand and it perfectly oscillates my entire body when I lay down in bed. Two good speeds and isnt loud. I dont like light or sound when I sleep and can still easily fall asleep with it there on next to me.
They're not kidding...this fan is SLIM!
Need a fan with a physical on-switch for this.
Perfect for a desk fan, or on a night table.
For the money, though, this fan is just right for my workspace.
Other than the tipsy issue, this is a great fan at a great price.
I albolutely LOVE this fan and couldn't be happier with my purchase! !
Answer: Yes, it works fine on its side but the oscillating function is pretty useless if you do so. I actually laid mine down on its side for a while and has no issues.
