I have spent hundreds of dollars on plumbers, due to clogged drains. No matter what, hair is always the culprit. When I tried this little device, I was a little apprehensive. It looks like a thread spool. But I tried it, and was pleasantly surprised. Just put into the drain while showering, and you are proactive with preventing hair from clogging the drain. Pull it out of the drain, clean the hair accumulation, and voila!. Love it! [This review was collected as part of a promotion.]
