We have about 10 spinners in total but this one is the best. My 4 year old collects them. This one has a long spin time and lots of light patterns. Cool both in light and in the dark. I’m so glad I got this spinner for him. Well worth the money.

Ex Output:
positive


Ex Input:
I'm so glad I stumbled across this product, because it has seriously improved my WiFi speed. Using it on an older laptop , I noticed that WiFi speed was faster than the built-in WiFi . I later tried it on an older desktop and it was very fast as well. An excellent product!

Ex Output:
positive


Ex Input:
This is a book written, not by some combat hero, but by a normal American infantryman. The experiences and feelings the author shares are those shared by thousands of similar veterans, many of whom assumed that they alone felt this way. His conflicted feelings about the war and his duty to those he served with along with the many years it took to come to terms with how he felt will resonate with many who served during this conflict.

Ex Output:

positive
