Fluid Audio F4F4 F Series The Fluid Audio F4 is the perfect entry level near field monitor for the aspiring musician or seasoned Pro. That's not to say this is not a professional monitor, however. One can look at it as just a shrunken down F5 as it uses the same silk dome tweeter and waveguide. The same amount of time and effort that went into our bigger models was invested in the F4 as well. The result: Great imaging, clear articulate midrange and ample bass that

the problem with these "cooling" pillows is any cooling effect is almost completely negated by a pillow case. this particular pillow is cool to the touch, but completely useless as it flattens out completely, way too soft I think for anyone. I would not recommend this "NASA" pillow for anyone for anything. Maybe for 10 bucks, but certainly not what they ask for this. I did keep it though. It is "cool" but only for a moment and your flipping it around like any other pillow. also way too soft. BUt, it has been cool enough to get me back to sleep.

I cannot say enough how happy I am with these pillows. Truly amazing. I put REST pillowcases on them and they are constantly cool/cold.

Love it

Set name: UltraCool Pillow, King - Soft/Medium Firmness, Item length width: 40.0 Inches

I really like this pillow!! It’s a nice medium fluff. I do think it feels cooler. And, when you flip to the “cool side of the pillow” it’s realllly chilly. It’s very long - it sticks out of my king size pillowcase a little bit - but not enough to be bothered by it.
