Input: Consider Input: The connection with my iPhone was very smooth and easy. There is no lag and the sound quality is superb. It last days with full charge. Looks very sophisticated.

Output: positive

Input: Consider Input: Look out. I've used these for several years and the colors are no longer red, dark blue, yellow and dark purple. I received neon green, orange, aqua blue and fuchsia pink. Dark purple was okay for my little guy, but bright pink isn't going to work. Will either have to use one old car from last school year or order another set to have four. I put two under a yumbox and two on top in a lunchbox. Others are right about not staying cold long, but works great to keep non perishable items cold.

Output: positive

Input: Consider Input: This book is very interesting and rich of nice examples that, altogether, give a really good idea about how complex and vast software development is, but also how much fun it can be. Definitely recommended for those who like to learn by doing.
Output: positive
