Love the feel of the sheet set but very disappointed in the cooling effect that your website describe. It is not at all cooling when sleeping. In fact tit gets really warm and still waking up sweating. This purchase was completely unsatisfied. I washed it so I have to keep it. I am very disappointed in this product.

Ex Output:
negative

This small vacuum cleaner is really powerful enough to clean the dirt / food particles in car. Cleans well even in the small gaps between seats. The long pipe accessory makes it easy to clean below seats. This works well even without the car engine off in my crossover. And the long cable helps clean inside as well as outside the car. The filter is easy to remove and clean. A must have item.

Ex Output:
positive

I have purchased 3 of these. I bought a red one for myself & loved it so much that I ordered a stainless one for my Father my husband asked where his was so I ordered him a stainless one. My red one keeps things very cold & holds ice nicely all day! My Dad lives in another city so I don't have 1st hand knowledge of his. My husband really didn't use his so recently I have started using it some while mine is being washed. His stainless does not hold ice & the outside has condensation. It's too late to return thru Amazon so I'm hoping that the manufacturer of COLD 1 will reach out to me so that I can exchange this.
