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: Great quality, fit tight just like OEM. Awesome seller too. Offered to replace for free when I broke a tab off one of the caps during installation. No worries here!

positive
