Example Input: Hair keeps clogging up my bath shower drain and the sink constantly. I needed to get a snake drainer as a recommendation from a friend. Decided to get this since it comes in sets of two. I tried it out and was able to pull out some hair. My sink and shower drain started to unclog. Glad that this worked! Glad this worked out!
Example Output: positive

Example Input: 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.
Example Output: positive

Example Input: I do a lot of hot yoga so its like this was made for me. I really needed a product that would absorb the sweat as I do sweat a lot when doing hot yoga. This mat is a great size, very absorbent and suits my need perfectly.
Example Output:
positive
