I like the dark gray color and overall look of the sheepskin. This seems well made, but unfortunately gets too hot for me and within minutes. I ended up flipping it back and forth to get a 'cooler' side for the duration of the ride, eventually giving up and removing it. And it wasn't even warm/sunny. The search continues.

Ex Output:

Ex Input:
They're Easter-themed, but only about half the items are sized to fit in Easter eggs. (If I'm filling Easter eggs for ten kids, I'm not also going to make them favor bags.) Otherwise, it's about what I expected based on what I paid: the items are fine, the whistles whistle and the tops spin. The nicer items were fewer in number: I got two wind-up chicks in my bag and saved them for my own kids' Easter baskets, and four little wheely bugs.

Ex Output:

After reading the cookbook I am grateful for some of the designations provided by the editor. Certain recipes are indicated as light or fast to prepare. I do not want this, so I turned to this book. Thanks to the book, I learned how to balance myself pH, through which I can lose weight, fight fatigue, improve digestion and increase energy. The book is written very easily and understandably. Thanks to the author for the useful information.
