[EX Q]: 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!
[EX A]: positive

[EX Q]: Wearing everyday and overnight, this band is holding up great!!! The matte finish has rubbed off a bit and is now shiny, but the band looks and feels brand new. Many compliments. Would buy again.
